In the story, how do the dwarfs impact the development of the plot?

1. they give the king’s son the beautiful Snow White in the coffin as a present.
2. they trap Snow White in their cottage so that the queen can find her.
3. their care of Snow White allows her to grow stronger so she can defeat the queen.
4. they help Snow White recover each time the queen harms her and warn her not to let anyone into the house.

It's multiple choice so the answer is out of these four.
