Solution

The correct option is A every somatic cell and tissue of body produces pangenes which are heritable.
In 1868, Charles Darwin proposed Pangenesis, a developmental theory of heredity. He suggested that all cells in an organism are capable of shedding minute particles he called gemmules(pangenes), which are able to circulate throughout the body and finally congregate in the gonads.
