Sentence Correction (SC) | Re: Found in the wild only in Australia and New Guinea, powerful back legs

Yup, the "by" is fine in (D), since the "powerful legs with long feet" are what distinguish the kangaroos from other large mammals.

Here, we have a passive voice verb ("are distinguished"), and the "by" is used to indicate who or what is performing that action.
