Solution

The correct option is B Right ovary
Two ovaries are present in the embryonic stage of each female pigeon bird. Only the left ovary and oviduct persist in adult pigeon and this is the functional ovary. The right ovary disappears during development. It is believed that the evolutionary loss of one functional ovary is a weight-saving change that may have proved beneficial to flying birds like a pigeon.
Thus the correct answer is option B.
