The correct answer is: B.Commensalism.

In this relationship:

1.The egrets benefit by feeding on the insects that are stirred up by the cattle. The egrets get easy access to food (insects) without having to hunt for it themselves.

2.The cattle are unaffected by the presence of the egrets. The egrets don’t harm the cattle, nor do they provide any direct benefit to them.

Since one species benefits (the egrets) and the other is neither helped nor harmed (the cattle), this is a commensal...
