Identify the primary factor related to fossils, according to continental drift theory. A) The age of the fossils were similar across continents.
B) The fossils obtained across continents were of different ages.
C) Wegener was unable to get any fossil evidence across continents.
D) Wegener could locate fossils only in the continental boundaries that were matching each other.

I dont know for sure, but I would say B.

Explanation:

I say B, because across continents there have been numerous fossils found with different ages. You can even look up case studies, but the answer might not be B, its just a guess.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
