What is the difference between Newton's 2nd and 3rd law of motion? Are they related as in if I applied force so that an object accelerates, would it exert the same amount of force towards me?

Yes, they would.

I can't differentiate which law (best choice) to put on a test, cause I'm confused about the 2nd law and 3rd.
For instance, a rocket up in the air - would the best choice be law 2 or 3?

Both are needed for a rocket to fly. Which is the correct answer will depend on what the question is.
