Fossils of a whale that beached on an African shore more than a million years ago and was subsequently butchered by hominids have been recovered by palentologists.

OA : A

Killed B,C, b/c of S-V agreement has/have
Killed E b/c of S/V were used for a whale
Killed C b/c of which ..again..
Why is D wrong ?
I thought A broke the parallelism .. beached and was butchered...

Fossils of a whale having been beached?? Is it clear what beached.

Fossils/Whale?

Thats why need the modifier that to refer to whales
