D'après lui, l'habit ne fait pas le

The sentence D'après lui, l'habit ne fait pas le... ("According to him, the clothes do not make the...") is an incomplete French proverb. The full proverb is:

L'habit ne fait pas le moine.

This literally translates to "The habit (clothing) does not make the monk." It means that one should not judge a person's character or abilities by their outward appearance. It is the French equivalent of the English proverb "Don't judge a book by its cover."

The word moine (monk) completes the proverb. A monk's habit (robe) is distinctive, but wearing one does not actually make a person a monk - hence the proverb's lesson about appearances being deceptive.

The other options do not complete any known French proverb: style (style), prêtre (priest), and riche (rich person) are not part of this expression. While prêtre is semantically related to religious life, the established proverb specifically uses moine.
