The answer for this question is 2 and 3
I remembered one time I heard “If you want to look young and thin, hang out around fat old people.” Then I was WHAT?! and wondered if it would work.
The answer is motif :) any reoccurring theme, pattern, idea, image etc. in a work applies to this.
for example, an artist that includes flowers in across all of their work (or a series of it) would be depicting a floral motif. I hope this helps!!
