Answer: C

Explanation:

For a test network in Hyperledger Fabric, one ordering node is sufficient to form an Ordering Service7. The test network typically uses a single-node Raft ordering service for simplicity and educational purposes.​However, for production networks, a multi-node ordering service is recommended for fault tolerance and high availability8.
