Answer

Brief Explanations:

The text describes environments (volcanic craters, Antarctic soil) that lack nutrients and light. Such conditions are not favorable for most life forms. "Hostile to" means unfriendly or unfavorable, which fits the context. "Compatible with" (B) would imply the environments are suitable, which they are not. "Constrained by" (C) doesn't convey the idea of the environment being bad for life. "Derived from" (D) is about origin, not the environment's effect on life.

Answer:

A. hostile to
