Answer:
The overall answer that you want is: Male rotifers are extremely rare.
Reasoning:
"Rotifers are dioecious, which means that they have both male and female organisms. But, in most species, males have not been observed or are very rare."
Your welcome, have a good day!
Rotifers primarily reproduce through parthenogenesis because Male rotifers are extremely rare. Thus, the correct option is D.
What is Parthenogenesis?
Parthenogenesis may be defined as a kind of asexual reproduction through which an egg can develop into an embryo without being fertilized by a sperm. This process of reproduction supports the chromosomal theory of inheritance.
Parthenogenesis is significantly considered as the most stable, easy, and simplest process of reproduction.
Most of the species of rotifers consist only of females and due to this females follow the method of parthenogenesis in order to produce their daughter cells without the involvement of a male partner.
Due to the lack of a male population, the females of the rotifers typically follow this method of reproduction in order to give rise to their young ones.
Therefore, Rotifers primarily reproduce through parthenogenesis because Male rotifers are extremely rare. Thus, the correct option is D.
