I feel like I’ve seen similar questions before, and I’m leaning towards B as well. Double spending seems to be the key problem Blockchain addresses.

I’m a bit confused about the options. I thought anonymity was a big part of cryptocurrencies too, but maybe that’s not what this question is asking?

I remember practicing a question like this, and I think B is definitely the right answer. Double spending was a big concern before Blockchain.

I think Blockchain mainly solved the double spending issue, but I’m not entirely sure if it also impacts anonymity.
