Solution

The correct option is C Assertion is correct but Reason is incorrect.
Mutualism is the relationship between organisms of different species in which each individual benefits from the activity of the other. There are two types of mutualistic relationships, obligate mutualism and facultative mutualism. In obligate mutualism, one organism cannot survive without the other and the relationship is obligatory. In facultative mutualism, each organism can survive independently, but it benefits both to remain together.
So, the correct answer is option C.
