B. It was passed to the individual by a gamete from the father.

Explanation:

DNA is transferred to the next generation via gametes, which are produced during meiosis. During meiosis, half of the genetic material is transferred from parent cell to their gametes. Therefore, among the given options, only B is correct.

Option A is not correct because it talks about somatic cells; whereas, in somatic cells, genetic material is not transferred half rather duplicate first and then a complete duplicated set of genetic material is transferred.

Option C is also not correct because only one gamete (sperm) fertilizes the egg. Hence, not half of his cells descend from father gamete. Similarly, option D is also incorrect because it is not possible to descend half of the nuclei from the father to the offspring.
