Use a quote from the novel to further emphasize your point.
A. a photograph of elephants in a forest is your best answer choice.
Note that the report is about "<em>wild elephants</em>".
Using images of taming elephants or any pictures (or drawings) by humans generally don't give a wild vibe to it.
Not B, because it would seem that the elephant had interaction with the human.
Not C, because the "wild" part of the elephant is gone already (the elephant being tamed by humans and used for exhibition)
Not D, because the word "taming" is in there.

Laura judges Rita by looks instead of actually finding out by asking. Never judge a book by its cover as they say. Also Laura focused more on Rita than herself causing herself to fall behind. Hope it helped.
