Which of the following types of wireless attacks would be used specifically to impersonate another WAP in order to gain unauthorized information from mobile users?

An IV (Initialization Vector) attack targets the weak IV implementation in WEP encryption to crack the encryption key and does not involve impersonating an access point.

An evil twin attack creates a rogue access point that broadcasts the same SSID as a legitimate WAP, causing mobile devices to connect to the attacker-controlled network instead of the genuine one. Once connected, the attacker can perform man-in-the-middle attacks to capture credentials, session tokens, and sensitive data from users who believe they are on a trusted network.

War driving is the act of scanning for available wireless networks while in motion and does not involve setting up or impersonating any access point.

A rogue access point is an unauthorized AP connected to a network without permission, but it does not specifically impersonate an existing legitimate WAP the way an evil twin does.
