Answer: C. all the cells of an organism except the gametes
Explanation:
A somatic cell is any cell of the body except gametes, which can be a sperm or an egg, and undifferentiated stem cells. Also, they are diploid cells, and that means they contain two sets of chromosomes from each parent. So they form all the tissues of the body. Some examples of somatic cells are blood cells, skin cells, muscle cells, among others.
Undifferentiated stem cell are cells that can divide to produce other cells that are destined to differentiate, while gametes are haploid cells used during fertilization. Non of them are somatic cells.
