Swartkans territory CR

In Swartkans territory, archaeologists discovered charred bone fragments dating back 1 million years. Analysis of the fragments, which came from a variety of animals, showed that they had been heated to temperatures no higher than those produced in experimental campfires made from branches of white stinkwood, the most common tree around Swartkans.
Which of the following, if true, would, together with the information above, provide the best basis for the claim that the charred bone fragments are evidence of the use of fire by early hominids?
(A) The white stinkwood tree is used for building material by the present-day inhabitants of Swartkans.
(B) Forest fires can heat wood to a range of temperatures that occur in campfires.
(C) The bone fragments were fitted together by the archaeologists to form the complete skeletons of several animals.
(D) Apart from the Swartkans discovery, there is reliable evidence that early hominids used fire as many as 500 thousand years ago
(E) The bone fragments were found in several distinct layers of limestone that contained primitive cutting tools known to have been used by early hominids.

SPOILER: OA is E

A) can be eliminated

B) this answer choice, if true, would weaken the claim that the charred bone fragments are an evidence of the use of fire by the early hominids. Because, it is giving an alternative explanation (charred bone fragments could have been the result of a forest fire rather than of the use of fire by early hominids).

C) we already know from the text that these charred bone fragments come from a variety of animals. can be eliminated.

D) this choice does not answer the question whether early hominids used fire 1 million years ago or not.

E) the only possible solution.
We already know from the text that these charred bones came from animals. we also know that they were heated to high temperatures and most probably branches of trees in question had been used.
We only have to find the agents of the action. And only E gives the best choice.
