I remember studying this, and I think ERC20 is for currencies and ERC721 for collectibles. So, A seems right, but I hope I’m not mixing them up!

I recall that ERC20 tokens are all the same, but I’m not entirely sure about the specifics of ERC721. I think they represent unique items, like collectibles.

I'm a bit confused about the definitions. I thought both types of tokens could be unique in some way, but I guess ERC721 is definitely the one that's non-fungible.

I think ERC20 tokens are fungible, meaning they are interchangeable, while ERC721 tokens are unique. I remember practicing a question like this.

The key distinction is that ERC20 tokens are interchangeable, like regular currency, while ERC721 tokens are unique and non-fungible, like digital collectibles. This is an important concept to grasp for working with blockchain-based assets.

Wait, I'm still not sure I understand the difference. Are you saying ERC20 tokens are different, and ERC721 tokens are the same? I'm a bit confused by the wording here.

Okay, I think I got it. ERC20 tokens are fungible, so they're all the same, while ERC721 tokens are non-fungible, meaning each one is unique. That makes sense.

Option A makes the most sense to me. The non-fungibility of ERC721 tokens is what sets them apart from the fungibility of ERC20 tokens.
