Which choice completes the text so that it conforms to the conventions of Standard English?

A

species

B

type of species

C

species type

D

variety of species

Correct Answer: A

Choice A is the best answer. "Species" is the specific scientific term.

Choice B is incorrect because "type of" is redundant; a species is a type. Choice C is incorrect because "type" is repetitive. Choice D is incorrect because "variety" is unnecessary when "species" is used.
