Question

How would a student justify inferring that "indigenous” means "originating in a particular region”?

The word root “gen” means “earth,” and the suffix “-ous” means “someone who does something.”
The word root “gen” means “birth,” and the suffix “-ous” means “having the quality of something.”
The word root “gen” means “body,” and the suffix “-ous” means “the state or condition of something.”
The word root “gen” means “rule,” and the suffix “-ous” means “being filled up with something.”

Answer 1

The second option.

Etymology: indigenous = in- + gen (from Latin gignere “to be born”) + -ous. So gen = “birth” and -ous = “having the quality of,” giving “having the quality of being born in (a place)” → originating in a particular region.
