Which of the following answer choices contains a metaphor? a. his skin was sandpaper. b. the sun sparkled like a diamond. c. she wanted to be like the birds and fly away. d. they felt free when they ran through the doors.

It’s a because no ones skin is going to be like sandpaper unless he is at the beach.

A, ´cause if it has like or as it´s a Simile.  Unlike a metaphor, a Simile draws things together with a like or as.  Hope it helps.  I might be wrong, I´m a bit of a blonde lol.  But I am making an A in this class, so I know something.

Bmetaphor i think that’s the answer
