Final answer:
WTLS provides services similar to TCP and UDP for WAP.
Step-by-step explanation:
The correct answer is A. WTLS (Wireless Transport Layer Security).
WTLS is a security protocol that provides similar services to TCP and UDP for WAP (Wireless Application Protocol). It is designed to ensure the confidentiality, integrity, and authentication of data transmitted over wireless networks.
WDPC (Wireless Datagram Protocol Control) and WTP (Wireless Transaction Protocol) are other protocols used in WAP, but they do not provide services similar to TCP and UDP. WFMD is not a protocol used in WAP.
