Correct Answer:

The correct configuration for adding TSIG with the specified algorithm and key should be in the following format: ``` key <key_name> { algorithm <algorithm_name>; secret "<secret_key>"; }; ``` Based on this, the correct choice is C: ``` key.server.example.com. { algorithm hmac-md5; secret "skrKc4DoTzi/takIlPi7JZA=="; }; ``` This matches the required parameters: the key name, the algorithm (hmac-md5), and the secret key enclosed in quotes.
