Option B with Hyperledger Composer is an interesting approach, but I'm not sure if it's the only way to communicate with chaincode.

I think Option D is a bit too simplistic. Hyperledger Fabric has more complexity than just pointing to an IP address and calling a function.

Interesting point, Oretha. I can see how that could also be a valid approach. It's important to understand all the options.

Option A seems like the correct way to interact with Hyperledger Fabric chaincode. Using an SDK to invoke chaincode functions makes sense.

I disagree, I believe the answer is D. The app directly calls the chaincode address to initiate the write process.

I think the answer is A, because the app uses an SDK to interact with the chaincode and notify the necessary peers.
