The attempt at a solution
I think the answers are a. and c. It's definitely not b. or e., because those happen when the piston is near the top of the cylinder. I'm not sure about d. though. I think that also happens as the piston travels upwards.

Could someone please confirm my answers?

I'm pretty sure it's c and d. Take a look at this wiki article - http://en.wikipedia.org/wiki/Two-stroke_engine
