Answer:
C. There is no genetic drift
Explanation:
A population is said to be in genetic equilibrium when the genetic variation of a population remains constant over many generations.
For a population to remain in genetic equilibrium it is necessary that external factors that disturb the equilibrium should not be present.
The external factors that are responsible for disturbing the genetic equilibrium are mutations, non-random mating, genetic drift and gene flow.
Genetic drift occurs when due to a chance event the allele frequency of a population either increases or decreases and this is usually common in small populations.
Thus, genetic drift should not occur so that the population can be in genetic equilibrium.

Wegener proposed the hypothesis of continental drift, which suggested that continents are in constant motion on the surface of Earth. Over time Pangaea began breaking apart, and the continents slowly moved to their present positions.
<h3>What is Continental Drift ?</h3>
The theory of continental drift is most associated with the scientist Alfred Wegener.
- Wegener's continental drift theory introduced the idea of moving continents to geoscience. He proposed that Earth (opens in new tab) must have once been a single supercontinent before breaking up to form several different continents.
- The four pieces of evidence for the continental drift include continents fitting together like a puzzle, scattering ancient fossils, rocks, mountain ranges, and the old climatic zones' locations.

The first step in the formation of the human embrayo and it is called fertilization.
<h3>What is fertilization?</h3>
The first step in the formation of a human embrayo is called fertilization. The term fertilization has to do with fusion of the male and female gametes to form a zygote.
Hence, the diagram as shown is the first step in the formation of the human embrayo and it is called fertilization.
