Option C. Law of inertia.

Explanation:

Inertia is the property of a body to resist any change in its state of rest or motion. For example, if a person is running fast and suddenly his leg hit with a stone, the person falls in farward direction on the ground. The lower part of the body stops due to stone but the upper part of the body continues its motion due to inertia.

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
