Answer:
B. They reproduce asexually.
Step-by-step explanation:
Asexual reproduction often known as abiogenetic multiplication requires just one parent organism and results in hereditary identical progeny (similar to a new copy). Since there is no blending of genetic data required and organisms don't have to invest energy finding a mate, populaces can increment quickly because of asexual generation. Thus, with the guide of asexual generation, the energy needed in the process associated with multiplication and nurturing is diminished contrasted with sexual reproduction.
