The correct option is A. Resource partitioning refers to a situation in which living organisms live together in the same environment in such a way that it is easy for them to co-exist because they are not using the same resources. In the question given above, it will be easy for the two species of squirrels to co-exist because although both are feeding on acorns, they are not feeding on acorns from the same location; one feed on the ground, the other feed on the trees.
