A. Life is like a box of chocolates. 2. Simile

It uses 'like' in the sentence.

b. The world is just waiting for you to go enjoy it. 3. Personification.

It has elements of human characteristics, even though the 'world' is unable to feel such things.

c. Maybe Forrest Gump had it right about life. 1. Allusion

I hope this helps!
