Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion.
The assertion is correct as Bidder's organ is a spherical, brownish organ present in every member of the family Bufonidae (true toads). The organ is located just in front of the kidney. The reason is also correct as it does not have much significance in toad and the true function of the Bidder's organ remains a mystery.
Therefore, the correct answer is option B.
