Explanation

Port 500/UDP is used by IKE (Internet Key Exchange), the key management protocol for IPSec - making IPSec the correct first answer. L2TP (Layer 2 Tunneling Protocol) is commonly deployed over IPSec and uses UDP-based ports for its tunneling operations. L2TP/IPSec is a widely used VPN combination that requires IKE (500/UDP) for security negotiation. SSL uses TCP 443, Kerberos uses TCP/UDP 88, RDP uses TCP 3389, and PPTP uses TCP 1723 plus GRE - none of which match the ports listed.
