The correct option is D There are two parents.
Asexual reproduction produces individuals that are genetically identical to the parent plant. It does not involve two parents, instead only a single parent is involved in this process. In asexual reproduction, the organism reproduces on its own without the help of other organisms. Seeds are formed as a result of the fusion of male and female gametes which occurs in sexual reproduction. In plants, vegetative reproduction is a type of asexual reproduction where an entire plant is obtained from the vegetative parts of a single parent. Thus, the correct answer is option D.
