Miners choosing to 'accept or pass' on a transaction? Sounds like they're playing a game of blockchain poker or something.

Option D, 'None of the above'? That's a bit too easy. I'm going to have to think this one through more carefully.

Hmm, Option C seems a bit too broad. I'd expect a more specific answer that clearly outlines the correct order of the transaction lifecycle.

I'm not sure, but I think Option B might be more accurate. The transaction should be broadcast to the network first before the user signs it, right?

Option A looks correct to me. The transaction lifecycle follows a logical sequence starting with the user initiating the transaction, signing it, then the network validating and miners processing it.
