Answer

Correct option: D.
A large non $-$ motile female gamete and a small motile male gamete.
Oogamy is the common type of heterogamaous sexual reproduction in which the female gamete or egg cell is non$-$motile and significantly larger than the male gamete.
The male gametes on the other hand are motile spermatozoa that compete for fertilizing the non$-$motile egg.
Oogamy occurs in both plant and animals but also found in some protists.
