Years before the advent of plate tectonics―the widely accepted theory, developed in the mid-1960's, the holdsthat the major features of Earth's surface are created by the horizontal motions of Earth's outer shell, or lithosphere― a similar theory was rejected by the geological community. In 1912, Alfred Wegener proposed, in a widely debated theory that came to be called continental drift, that Earth's continents were mobile. To most geologists today, Wegener's The origin of Continents and Oceans appears an impressive and prescient document, containing several of the essential presumptions underlying plate tectonics theory: the horizontal mobility of pieces of Earth's crust; the essential difference between oceanic and continental crust; and a causal connection between horizontal displacements and the formation of mountain chains. Yet despite the considerable overlap between Wegener's concepts and the later widely embraced plate tectonics theory, and despite the fact that continental drift theory presented a possible solution to the problem of the origin of mountains at a time when existing explanations were seriously in doubt, in its day Wegener's theory was rejected by the vast majority of geologists.

Most geologists and many historians today believe that Wegener's theory was rejected because of its lack of an adequate mechanical basis. Stephen Jay Gould, for example, argues that continental drift theory was rejected because it did not explain how continents could move through an apparently solid oceanic floor. However, as Anthony Hallam has pointed out, many scientific phenomena, such as the ice ages, have been accepted before they could be fully explained. The most likely cause for the rejection of continental drift―a cause that has been largely ignored because we consider Wegener's theory to have been validated by the theory of plate tectonics―is the nature of the evidence that was put forward to support it. Most of Wegener's evidence consisted of homologies—similarities of patterns and forms based on direct observations of rocks in the field, supported by the use of hammers, hand lenses, and field notebooks. In contrast, the data supporting plate tectonics were impressively geophysical—instrumental determinations of the physical properties of Earth garnered through the use of seismographs, magnetometers, and computers.

The author of the passage suggests that the most likely explanation for the geological community's response to continental drift theory in its day was that the theory

Awas in conflict with certain aspects of plate tectonics theory
Bfailed to account for how mountains were formed
Cdid not adequately explain how continents moved through the ocean floor
Dwas contradicted by the geophysical data of the time
Ewas based on a kind of evidence that was considered insufficiently convincing

然而这句到底说了什么还是不懂

最可能导致当时的人们拒绝“continental drift”的原因——这个原因之所以被我们（现在的人）很大程度的忽视是因为我们现在知道了plate tectonics，里面有一些前提让我们觉得Wegener的假说是对的（插入语，站在作者即现在的人角度说的）——是有一些他作为假设前提的证据是在当时没有被发现或者证明的

这道题定位its lack of an adequate mechanical basis居然选对了。。。其实however后面才是真正的原因，The most likely cause for the rejection of continental driftis the nature of the evidence that was put forward to support it. 接着对比W和P的证据，说明W的证据不足。所以选E

Wegener\'s theory is based more on evidences while plate tectonics is supported by data, computer analysis, etc (introduced later in the last paragraph). Since people tend to believe in the data & analysis > evidences, plate tectonics theory owns more supporters.

However, as Anthony Hallam has pointed out, many scientific phenomena, such as the ice ages, have been accepted before they could be fully explained. 这是说，C句里给的原因不成立，因为ice ages 在被fully explained 之前就被人们所接受，所以说continental drift被拒绝的原因不是它没有完整的解释how to move through an apparently solid oceanic floor
