C Correct answer
Explanation

The ORA-12533 error specifically indicates illegal ADDRESS parameters in the TNS connect descriptor. You need to verify the protocol-specific parameters (PORT, HOST, etc.) in the ADDRESS section of tnsnames.ora. The service name (B, D) is irrelevant to this specific error.
