Answer: C

Explanation:

Intercommunication in Hyperledger Fabric regarding how smart contracts update the World State database is primarily achieved by calling other smart contracts, both within the same channel and across different channels. This process allows smart contracts, also known as chaincode, to interact and transact across the network, updating the World State as necessary based on business logic defined in the contracts. This capability is crucial for complex business processes that span multiple contracts and possibly multiple channels. Unlike setting endorsement policies or configuring peer-to-peer options, calling other smart contracts directly facilitates dynamic and direct interaction between business processes, enhancing the modularity and efficiency of the network. Cross-channel communication must be carefully managed within the permissions and policies defined in the network to maintain security and integrity.
