Often a type of organ or body structure is the only physically feasible means of accomplishing a given task, so it should be unsurprising if, like eyes or wings, that type of organ or body structure evolves at different times in a number of completely unrelated species. After all, whatever the difference of heritage and habitat, as organisms animals have fundamentally similar needs and so _______.

Summary
An organ or body structure is often the only mean of accomplishing a task. It is unsurprising that a type of organ or body structure may evolve at different times in unrelated species. Animals share fundamentally similar needs despite differences in heritage and habitat.

Strongly Supported Conclusions
Different animals may develop similar organs to accomplish the needs they share.

A
will often live in the same environment as other species quite different from themselves
This is unsupported because the stimulus provides no information to predict where different animals will live.
B
will in many instances evolve similar adaptations enabling them to satisfy these needs
This is strongly supported because we are told that sometimes an organ or physical structure is the only way of accomplishing a function. So if different animals have the same functions they need to accomplish, they may develop similar organs to accomplish those functions.
C
will develop adaptations allowing them to satisfy these needs
This is unsupported because although needs may be satisfied through adaptations, answer choice B does a better job of noting that the similarity of needs will likely result in a similarity of adaptations.
D
will resemble other species having different biological needs
This is antisupported because if other species have different biological needs, and needs may be met with unique organs designed for specific functions, species with different needs would likely develop organs that do not resemble each other’s.
E
will all develop eyes or wings as adaptations
This is unsupported because we don’t know that the common needs all animals share would be satisfied by eyes or wings.
