Explanation

SSL employs a hybrid encryption model: public key (asymmetric) cryptography handles the handshake phase - authenticating parties and securely exchanging session keys - while symmetric encryption handles the bulk data transfer, providing fast, efficient communication privacy and message integrity. This two-method design gives SSL both the security of asymmetric crypto and the speed of symmetric crypto.

Why the distractors are wrong:

• B. IPsec is a separate network-layer protocol suite used for VPNs; it operates independently of SSL and is not a component within it.
• C. MS-CHAP is a Microsoft-specific challenge-handshake authentication protocol used in PPP/dial-up and VPN contexts, not a mechanism SSL uses internally.

Memory tip: Think of SSL as a "handshake then highway" - the public key locks down the handshake (slow but secure authentication), then both sides switch to a symmetric key for the high-speed highway of data transfer. If an answer mentions a full separate protocol (IPsec) or a PPP-era auth protocol (MS-CHAP), it's describing something beside SSL, not inside it.
