<h2>b) is the correct option </h2>
Explanation:
The biological species concept defines a species as a group of individuals living in one or more populations that can potentially interbreed to produce healthy, fertile offspring
- The biological species concept connects the idea of a species to the process of evolution
- Because members of a species can interbreed, the species as a whole has a common gene pool, a collection of gene variants
- In order to be considered to be a single species in the biological species concept, a group of organisms must produce healthy, fertile offspring when they interbreed
- In some other cases, organisms of different species can mate and produce healthy offspring, but the offspring are infertile, can’t reproduce
Hence it includes the groups which are reproductively isolated so asexual fungi will be least relevant to this group
