The correct option is A Pigeon
The male pigeon has a pair of oval testes. From each testis the vasdeferens arises that ends into a seminal vesicle. It passes back and opens into the cloaca. There is no copulatory organ. In female pigeon, only the left ovary persists in the adult as the right ovary disappears during development. Fertilization is internal and takes place through cloaca (analogous to the anus in humans). Thus the correct answer is option B.
