Fish, frogs and most aquatic annimals release their eggs and sperm into the water for fertilization. However, may organisms, specially terrestrial animals, have evolved internal fertilizatioon. All of the following are advantages of internal fertilization, except:

a. Fertilization can occur outside of water but inside the organism

b. Once inside, the embryo may continue to develop internally

c. It requires the evolution of fewer specialized structures for reproduction

d. It makes it more likely that the eggs and sperm will find each other

c. It requires the evolution of fewer specialized structures for reproduction

Explanation:

Internal fertilization refers to the process of fusion of eggs and sperms inside the female body. The fusion of gametes mostly occurs inside the female reproductive tract during internal fertilization. This poses a need for the evolution of compatible reproductive structures in both genders of the internally fertilizing species to ensure that the sperms are deposited in or near the female reproductive tract.
