The correct answer is C. 46.
A human cell contains 46 chromosomes, which are found in the nucleus. Chromosomes are made up of DNA, which is the genetic material that contains

The number of chromosomes in a cell can vary depending on the type of cell. For example, sperm cells and egg cells only have 23 chromosomes each. This is because when a sperm cell fertilizes an egg cell, the resulting cell (a zygote) has 46 chromosomes.
The number of chromosomes in a cell can also change due to a genetic disorder. For example, people with Down syndrome have an extra copy of chromosome 21.
Chromosomes are important because they contain the genetic information that determines a person’s physical characteristics, such as hair color, eye color, and height. They also play a role in determining a person’s risk of developing certain diseases.
