Answer 1

(a) Frog shows external fertilization.

• The female frog releases several eggs in the water which are then fertilized by the male frog.
• A number of the eggs released by the females are destroyed by various sources such as predators , washing away by water etc.
• Only some of the eggs have the ability to survive which are fertilized by the male frog.
• As the process of fertilization occurs outside the body of the frog, hence it is external fertilization.

Thus, the correct option is (a) Frog.
