Suggested answer: A

Explanation:

A Security Association (SA) in the context of IPsec is a one-way logical connection used for secure communication between two endpoints. IPsec requires two SAs to establish a secure, bidirectional communication channel---one for each direction (inbound and outbound). This arrangement ensures that each direction is independently secured, with its own set of security parameters.

Reference:

RFC 4301, 'Security Architecture for the Internet Protocol'.
