Explanation
WPA2 (C) - Wi-Fi Protected Access 2 - provides the highest level of confidentiality among the options because it enforces strong cryptographic encryption of all data in transit over the wireless link, using AES in CCMP mode. Confidentiality is achieved through encryption; WPA2 ensures that even if frames are captured, their content cannot be read without the key. Disabling SSID broadcast (A) is security through obscurity - the network can still be discovered through passive sniffing of client probe requests, and disabling the broadcast does not encrypt any traffic. MAC filtering (B) is an access control measure, not an encryption mechanism; it does not protect the confidentiality of data on the wire. Packet switching (D) is a fundamental networking concept describing how data is routed and has no inherent confidentiality properties.
