I vaguely recall something about ECDSA being important for security, but I don't think it directly relates to how consensus is reached.

I feel like option B makes the most sense since all nodes need to agree, but I could be mixing it up with another topic we covered.

I remember practicing a question about miners validating transactions, so I might lean towards option A, but it feels a bit vague.

I think consensus is reached by every single node, but I'm not entirely sure if that's the only way it can happen.

Option B sounds plausible, but I'm not totally confident that's the right approach. I'll review the material again to make sure I understand the consensus mechanism.

The ECDSA signature algorithm is important for security, but I don't think that's the key to how consensus is reached. I'm leaning towards A or B.

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