Scientists change the names of taxonomic groups to match current nomenclature.
Answer: Option A.
Step-by-step explanation:
There are various main reasons why the taxonomists from time to time require or choose, to modify the name of an organism such as a plant. Initially the naming of the plant is treated by the set of laws (The International code of botanical nomenclature). It sets out how to correctly name the plants and how to solve the cases where two or more names have been used for one specie.
It seldom happens that applying the rule requires us to change the name. For example, if a specie named by one botanist turns out to have been before legitimately named by an elder botanist.
