Option A : The last word impacting makes the sentence not sound proper...

Looking for split we have 3-2 spilt : that and of ..

as the sentence is stating idea we have to use the that instead of of.. hence c and D is incorrect.

B : Subjunctive mood hence we have used have ....

Sorry, there is no subjunctive mood here. For subjunctive mood to be there, the sentence requires a compulsion, there is no compulsion involved here. This is mere statement. For converting this statement into a subjunctive mood, we may hve to say, though absurdly—

A piece of limestone discovered in sedimentary deposits near Gubbio, Italy, in 1979 demanded/ stipulated/ claimed the first evidence that the extinction of dinosaurs be caused by a meteorite impacting

Coming to other aspects, by meteorite impacting (impacting is gerund here) means a meteorite’s impaction or impact. It is not correct to use an ing gerund where a more befitting straight noun form is available. C is wrong because of the use of being caused as if the impact is happening now. D is a convoluted sentence. E has no completed verb.

Therefore, B survives.

ERROR ANALYSIS -

1) 'limestone provided the evidence' - action in the past, past tense should exist further
2) Use of 'possibly' - expected

A) meteorite impacting - wrong
B) CORRECT
C) Use of being is not correct
D) Too wordy
E) Change of voice
