Which is the CORRECT way to punctuate the sentence?
A. This native fish is only about three to four inches long
B. This native, fish is only about three to four inches long.
C. This native fish is only, about three to four inches long
D. This native fish is only about three to four inches long.

I believe the answer would be D

Explanation:

'A' was immediately dropped out for the lack of a period at the end.

Think about what a comma is supposed to do, It's supposed to have a small pause in a sentence. If you read everything out loud It would be awkward to pause in the places the commas are suggested. Thus, inclining me to think the correct answer is D.

Hope this Helps!
