Explanation

IPsec (Internet Protocol Security) is an open, IETF-standardized framework of protocols that provides authentication, integrity, and encryption for IP communications. It is the most widely used protocol suite for building secure VPN tunnels and operates at the network layer, enabling secure end-to-end communications. RSA is an asymmetric encryption algorithm, not a VPN protocol framework. L2TP (Layer 2 Tunneling Protocol) provides tunneling but has no built-in encryption - it is often paired with IPsec for security (L2TP/IPsec). PPTP (Point-to-Point Tunneling Protocol) is a Microsoft-developed protocol with known security weaknesses and is not an open standard. IPsec's open-standard nature and strong security capabilities make it the correct answer.
