IMO E

A and B makes improper use of which. it looks like it is descibing america.

In D, "it marks" it has no referant

C is using causing...... Looks like salmming and causing happened at same time. Actually, it slammed and salmming caused extinction.

Hence E is proper.

Which should be used to modify the noun that comes before.
In option B Which is trying to modify the cluase before. so B s out.

It is option E because plant and animal excinctions that mark
Proper verb is used
