Answer:

Correct Answer: C

Solution:

Toads have a Bidder’s organ anterior to each gonad, it atrophies in adult females but persists in males, and in either sex it can develop into a new ovary.

If testes are removed, the Bidder’s organs become ovaries in the male, they become functional so that there is a complete sex reversal.

It shows that Bidder’s organs have an important role in sex reversal in toads.
