I’m confused about the order; I thought the transaction was broadcasted first, but I guess it’s more about the signing process. Maybe option C is possible?

I practiced a similar question, and I think both A and B have some valid points, but I lean towards A being correct.

I'm not entirely sure, but I feel like the transaction needs to be validated by the node before it's sent out to the network.

I remember that the user usually signs the transaction before it's broadcasted to the network, so I think option A makes more sense.
