which situation could lead to the evolution of a population?

A butterfly population includes both green and yellow butterflies and a predator sees yellow more easily than it does green.
This is because the butterflies would adapt/evolve to be green rather than yellow to avoid predators

Option B

Explanation: There is a butterfly population that contains both green colored butterfly and yellow colored butterfly.

Predators prey and sees yellow colored butterfly more easily as compared to that of the green ones.

All the green butterflies will remain as evolution will lead to save green colored butterflies as they are hardly visible.

There will be a time when all the yellow colored flies will be lost due to evolution.

Yes a horse is a hervivore because it eat things such as plants, grass, and leave so yeah that explains it.
