Just a fact check, but isn't the JSON-RPC open source?

Wait, is the JSON-RPC really closed source? That sounds off.

I practiced a similar question, and I think the key point is that Web3.js simplifies the interaction with Ethereum nodes, which aligns with option A.

I feel like I read somewhere that Web3.js is necessary, but I can't recall if it was because of the closed source aspect mentioned in option B.

This seems like a pretty straightforward question about the Web3.js library. I'm going to go with option A, as it seems to best describe the purpose and functionality of the library.

I'm a little confused by the wording of this question. Is the JSON-RPC interface of Ethereum nodes closed source? I'm not sure if that's a relevant detail or not. I'll have to re-read the question and options carefully before answering.

Okay, I think I've got this. The Web3.js library is useful when developing distributed applications with HTML and JavaScript because it abstracts away the JSON-RPC interface of Ethereum nodes, making it easier to interact with the blockchain. I'm going to go with option A.
