Haha, summing up all the Ethers? That's a new one! Clearly, the nonce is used to prevent replay attacks. Option A for the win!

Wait, the nonce is used to sum up all the Ethers sent from that address? That doesn't sound right at all. I'll go with Option A.

I believe the nonce-field is also used to ensure the order of transactions from the same address.
