Detailed Solution

The correct answer is (b) Embryo

After fertilization, the zygote (single-celled structure formed by fusion of sperm and egg) starts dividing repeatedly through a process called mitosis.

These repeated cell divisions form a multicellular ball of cells, which gradually develops into an embryo.
The embryo later implants in the uterus wall, where it continues to grow and develop into a foetus.

Why Not the Other Options?

Foetus: A later stage of development after the embryo is well-formed and recognizable as a baby.
Gamete: Sex cells (sperm/egg) that combine to form the zygote, not produced from it.
Sperm: The male gamete, produced in testes, not from the zygote.

Thus, the zygote’s repeated cell divisions result in the formation of an embryo.
