Haha, the options are like a choose-your-own-adventure for blockchain nerds. I'm gonna go with the one that sounds the most 'cryptographically secure'!

The ECDSA algorithm in option C does sound like it could help with security, but I'm not sure if that alone ensures consensus.

Option B seems like a logical choice, as the whole network needs to agree on the transaction for it to be valid.
