Wait, are you sure? I thought they could be the same.

Definitely B, nonces change with each transaction.

Seems odd that they wouldn't be the same, but I guess it makes sense.

A is incorrect, signatures vary due to nonces.

I recall discussing how signatures are unique to each transaction due to the nonce, so I would go with B, but I'm a bit hesitant.

I practiced a similar question where the nonce was mentioned, and it definitely influenced the signature, so I lean towards B.

I'm not entirely sure, but I feel like I read that transactions with the same data should have the same signature, so maybe A is correct?

I think the answer might be B because I remember something about nonces changing with each transaction, which affects the signature.

I'm pretty confident the answer is B. The nonce is what makes each transaction unique, even if the data is the same.

I'm a bit confused on this one. I'll need to review the material on transaction signatures and nonces before I can decide.

B seems like the right answer to me. The nonce is a unique identifier for each transaction, so the signature would have to be different.

B is the correct answer, no doubt about it. The nonce is like the secret sauce that makes each transaction special.
