Solution
The correct option is A Sibling Sibling species are morphologically indistinguishable, but are reproductively
isolated.
Sympatric species occurs when there are no physical barriers
preventing any members of a species from mating with another and all
members are in close proximity to one another.
Allopatric species occurs when a species separates into two separate groups which are isolated from one another. A physical barrier, such as a mountain range or a waterway, makes it impossible for them to breed with one another.
Morphospecies is a group of biological organisms that differs in some morphological respect from all other groups.
