The correct definition of a "species" in biology refers to a group of organisms that can interbreed and produce fertile offspring under natural conditions. This emphasizes the concept that a species consists of populations of organisms that share similar characteristics and genetic information.

The reason why the third option is the most accurate is that it highlights the specific nature of biological classification, which categorizes living organisms based on distinct traits and reproductive capabilities. A species is not just any group or individual, but rather a well-defined category of organisms that are closely related and capable of reproducing within that group to maintain their genetic lineage.

Overall, understanding the definition of a species is crucial in various biological fields, including ecology, evolutionary biology, and conservation efforts, as it aids in the classification and study of biodiversity.
