Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
A phylogeny (or a tree of life) is a theory about how organisms are related to one another through evolutionary time.
Phylogenies are based on the assumption that more closely related species will be more similar to one another, and they are commonly built using genetic sequences or physical characters.
Hence, Phylogeny is the developmental history of a species which is the basic unit of taxonomy.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
