Zygote
Correct Answer:
A. Male gamete
Explanation:
The correct answer is Option A: Male gamete.
In sexual reproduction, germ cells (gametes) are specialized reproductive cells. The male gamete, commonly known as a sperm cell, is characterized by its motility. It typically possesses a long, whip-like tail called a flagellum that allows it to swim through fluid environments to reach the female gamete. In contrast, the female gamete (egg or ovum) is generally much larger and non-motile, containing stored nutrients to support the initial stages of development after fertilization. While embryos and zygotes are stages of development following the fusion of these cells, the term "motile germ cell" specifically identifies the male gamete.
