Option A: Wrong
No statement inference could be drawn here as it does not agree with the mode of intuition meant for the passage.
Option B: Right
The statement here, emphasizes more on the head-word ''elephant''. Another emphasis was placed on the ''subordinate clause'' that gave rides to children at zoo'' which ensures it has a perfect fit in the main clause.
Option C: Right
Here, the use of article ''an'' and ''the'' in this sentence. ''The'' means the elephant has been previously discussed and the reader would have understood what the writer meant by the ''the elephant'' and not ''an elephant''.
Option D: Wrong
Here, the use of the conjunction ''and'' gave the statement a new dimension, meaning and thus incoherent and inconsistent with the passage tone.
Option E: Wrong
This statement is clearly non-definitive, no clear direction and the head-word does not infer to make a difference. it's grammatically inconsistent with the original statement.
