Ensure port 445 is open: The SMB protocol requires TCP port 445 to be open; connections will fail if port 445 is blocked.

When you create an Azure file share in a storage account, it uses the SMB protocol, which runs on port 445. SMB (Server Message Block) is a protocol used for file sharing and network communication between computers.
In order to map a drive to the Azure file share from a home computer that runs Windows 10, the computer must be able to connect to the Azure file share using the SMB protocol on port 445.
Ports 80 and 443 are used for HTTP and HTTPS traffic respectively. They are not used for file sharing.
Port 3389 is used for Remote Desktop Protocol (RDP) traffic. It is not used for file sharing and should not be opened for this purpose.
Therefore, the correct answer is C. 445.
