Answer 1

The correct option is A Species

• The biological species concept is the most widely accepted species concept. Ernst Mayr defined a species as 'species are groups of interbreeding natural populations that are reproductively isolated from other such groups'.
  
• The biological species concept explains why the members of a species resemble one another, i.e. form phenetic clusters, and differ from other species.
  

So, the correct option is 'Species'.
