Answer: D

Explanation:

To determine the correct Security Association (SA) in the context of IPsec, several elements are required:

SPI (Security Parameter Index): Uniquely identifies the SA.

Partner IP address: The address of the endpoint with which the SA is established.

Protocol: Specifies the type of security protocol used (e.g., AH or ESP). All these components collectively define and identify a specific SA for secure communication between parties.
