Answer:
Correct Answer: C
Solution:
Toads have a Bidder?s organ anterior to each gonad, they atrophy in adult females but persist in males, 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 toad.
