Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The biological species concept states that
A
organisms are part of the same species if they breed
B
organisms are part of the same species if they look the same
C
organisms are part of the same species if they can produce fertile offspring
D
organisms are part of the same species if they look the same and act the same
Explanation: 

Detailed explanation-1: -According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.

Detailed explanation-2: -The biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance. Although appearance is helpful in identifying species, it does not define species.

Detailed explanation-3: -The Biological Species Concept defines a species taxon as a group of organisms that can successfully interbreed and produce fertile offspring. According to that concept, a species’ integrity is maintained by interbreeding within a species as well as by reproductive barriers between organisms in different species.

Detailed explanation-4: -The biological species concept states that a species is a group of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups.

Detailed explanation-5: -Option C: According to the biological species concept, phenotypic similarities are not required for two populations to be considered the same species, interbreeding between them is necessary. Therefore, this is an incorrect option.
