Show answer and explanation

Correct answer: (C) A food source; possible protection from poachers.

Explanation

Eating ticks provides food to the birds, while the alarm may allow rhinos to avoid poachers. These are exactly the two benefits in C. The passage does not say the birds save poachers or receive no reciprocal benefit.
