Answer: A. 22
The correct answer is A. When configuring an NSG for inbound access from Azure Bastion to virtual machines, you need to allow SSH traffic (port 22) for Linux VMs or RDP traffic (port 3389) for Windows VMs. Since the question does not specify the operating system of the VMs, we assume it's a Linux VM. Therefore, SSH traffic must be allowed, which uses port 22.
