So, ERC20 tokens are like dollar bills, all the same, while ERC721 tokens are like unique pieces of art. Got it!

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.

I agree with Nobuko. The key difference is that ERC20 tokens are interchangeable, while ERC721 tokens are not.

That makes sense. Fungible means each token is the same, while non-fungible means each token is unique.

Option A is the correct answer. ERC20 tokens are fungible, meaning they are all the same, while ERC721 tokens are non-fungible, meaning each token is unique.
