Solution
The correct option is B
Hermaphroditism
A hermaphrodite is an organism that has both male and female reproductive organs and can carry out the role of both the male and female organism during the course of reproduction. In some hermaphrodites, the animal starts out as one sex and switches to the other sex later in its life like in the case of clown fish. A school of clownfish is always built into a hierarchy with a female fish at the top. When she dies, the most dominant male changes sex and takes her place. Unisexuality is the quality of possessing a single sexual characterisitic, that is having either the male or female organs in one individual. And sexual dimorphism is exhibiting distinct difference in size or appearance between the sexes of an animal in addition to the sexual organs themselves.
