Critical Reasoning

Impact craters caused by meteorites smashing into earth, have been found all around the globe but they have been found in the greatest density in geologically stable regions. This relatively greater abundance of securely identified craters in geologically stable regions must be explained by the lower rates of destructive geophysical processes in those regions.
The conclusion is properly drawn if which one of the following is assumed?
(A) A meteorite that strikes exactly the same spot as an earlier meteorite will obliterate all traces of the earlier impact.
(B) Rates of destructive geophysical processes within any given region vary markedly throughout geological time.
(C) The rate at which the Earth is struck by meteorites has greatly increased in geologically recent times.
(D) Actual meteorite impacts have been scattered fairly evenly over the Earth's surface in the course of Earth's geological history.
(E) The Earth's geologically stable regions have been studied more intensively by geologists than have its less stable regions.
OA after sometime

rocks hit earth uniformly, some places the marks got erased but some other places they exists like that

A/B are the only contenders and B>A
some marks are erased quickly is what B says and the argument havent given us clue if multiple rocks hit the same spot

2.05min

IMO D.

If the hitting is fairly even on across the global then we can say that it hits on geologically stable areas.

tricky passage but if you ignore all the science wordings for a moment becomes failry simple.
IMO D (arrived by POE)
the stimulus is based on the assumption that meterorites are scattered evenly. if thats not the case, may be the meteorites always struck at one place and it hapens to be geologically stable regions, conclusion does not hold good then.

OA is D
if u negate the option---Actual meteorite impacts have not been scattered fairly evenly over the Earth's surface in the course of Earth's geological history. -----would actually destroy the conclusion(This relatively greater abundance of securely identified craters in geologically stable regions must be explained by the lower rates of destructive geophysical processes in those regions. )
