Correct Option: B
Explanation:
A habitat is the type of natural environment in which a particular species of organism lives and is characterized by both physical and biological features. A 'species' habitat are those places where a particular species can find food, shelter, protection and mates for reproduction. Every organism has certain habitat needs for the conditions in which it will thrive, but some are tolerant of wide variations while others are very specific in their requirements. A habitat is not necessarily a geographical area, it can be the interior of a stem, a rotten log, a rock or a clump of moss, and for a parasitic organism it is the body of its host, etc.
So the correct option is 'habitat'.
