The correct answer is: B.Mutualism.

In this case:

1.The oxpeckers feed on the ticks found on the rhinos, benefiting by getting a meal.

2.The rhinos benefit as well, since the oxpeckers help remove the ticks, which can be harmful and cause irritation.

This is a mutualistic relationship because both species gain a benefit:

The oxpeckers get food (the ticks).

The rhinos get pest removal (relief from the ticks).
