Wait, we're supposed to be solving coding problems, not writing comedy skits! Although, I do have a killer 'Promise' pun up my sleeve...

I'm with Deandrea on this one - the 'await' keyword had me thrown off at first. But C) is definitely the right answer here.

Hmm, I'm a bit confused. I thought the code would run the promises sequentially, but C) makes sense. Time to review my async/await knowledge!

This is a tricky one! The correct answer is C) - aPromise and bPromise run in parallel. I think the key is understanding how async/await works with Promises.

But doesn't the 'await' keyword make them run sequentially? I'm sticking with my answer.
