Totipotency is defined as the ability of a single cell to get differentiated, including extraembryonic tissues. Totipotent cells formed during sexual and asexual reproduction include spores and zygotes. Thus, each totipotent cell is a self-contained entity that can give rise to the whole organism.
So, the correct answer is option B.
