I'm not sure, but I think it could also be D) Submit, as it sounds like it could be used to submit changes to the ledger.

I agree with Vicki, because the Invoke API call is used to update ledger state.

Hmm, I think B) Invoke is the correct answer here. The Fabric Gateway client API allows you to invoke smart contract functions to update the ledger state.
