Option D.) “Somatic cell mutations are not passed to the next generation” is correct.
Somatic cells, also known as body cells, undergo a mitotic process of cell division in which only one division takes place. Unlike somatic cells, gametes (otherwise known as sex cells) go through cell division twice in a process known as meiosis. Somatic cells differ from gametes because essentially, somatic cells undergo mitosis which doesn’t pass the mutations down to the next generation.
