Answer:

(a) False

This statement is false because oviparous animals lay eggs and viviparous animals give birth to young ones.

(b) True

This statement is true because each sperm is a single cell and an egg is also a single cell.

External fertilization takes place outside the female body; they lay eggs and then eggs got hatch and young ones are produced. So, this statement is true that external fertilization takes place in frogs.

(d) False

This statement is false because a new human individual develops not from a cell called gamete. A new individual is formed due to the fusion of two single cells i.e. sperm and egg.

(e) True

Yes, this statement is true because egg is a single cell.

(f) False

This statement is false because amoeba reproduce by binary fission. It is a type of asexual reproduction.

(g) False

This statement is false because fertilization only occurs in sexual reproduction, not in asexual reproduction.
