Question

what does the prefix \a-\ mean, as in abiotic? without/not life/living study of

Explanation:

To determine the meaning of the prefix "a - " in "abiotic", we analyze the word "abiotic". "Biotic" relates to life (from "bio - " meaning life), so "a - " here should mean the opposite. "Without/not" fits as "abiotic" means non - living or without life. "Life/living" is the meaning of "bio - ", not "a - ", and "study of" is not related to this prefix.

Answer:

A. without/not
