Question

Is an interspecific association in which all species involved benefit.

• A. Commensalism
• B. Mutualism
• C. Competition
• D. Parasitism

Answer 1

The correct option is B Mutualism

A.Commensalism - an association between two organisms in which one benefits and the other derives neither benefit nor harm

B.Mutualism is an association between organisms of two different species in which each benefits. Mutualistic arrangements are most likely to develop between organisms with widely different living requirements. Mutualism plays a key part in ecology. Measuring the exact fitness benefit to the individuals in a mutualistic relationship is not always straightforward, particularly when the individuals can receive benefits from a variety of species.

C.Competition - the activity or condition of striving to gain or win something by defeating or establishing superiority over others.

D.Parasitism - relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing the host organism.

So the correct option is 'mutualism'.
