I feel like the nonce-field might also have something to do with checksums, but that doesn't seem right for this question.

The nonce is there to prevent replay attacks, right? I'm pretty sure that's the main purpose, so I'll go with option A.

Wait, I thought the nonce was used for something else, like verifying the transaction or something. I'm not totally confident in my answer here. I'll have to guess and hope for the best.

Okay, I remember learning about the nonce in class. I believe it's used to ensure each transaction is unique and can't be replayed. I'll select option A.

Hmm, I'm a bit unsure about this one. I know the nonce has something to do with preventing double-spending, but I can't remember the exact purpose. I'll have to think this through carefully.

I'm pretty sure the answer is Trojan, since that's the type of malicious code that can give a hacker control over a victim's system files.

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.
