The correct answer is:

Oogamy is a specialized form of sexual reproduction (a type of heterogamy) characterized by a significant difference in the size and motility of the male and female gametes.Female Gamete (Ovum/Egg): It is typically large because it stores nutrients for the developing embryo and is non-motile (stationary).Male Gamete (Sperm/Spermatozoon): It is small and motile, often equipped with flagella that allow it to swim through a medium to reach and fertilize the egg.
