Unlike previous hypotheses concerning climate changes,modifier,so eliminate a and b straightaway.Down to c,d and e.
C:this time citing a lethal comet as the cause of the extinction
eliminate as wordy.
Left with d and e.
:as the cause of dinosaur extinction???Improper meaning.
So the answer should be D as stated by others too.
