Which of the following software types should a user install on a smartphone if the user does not want communication to be readable when accessing the Internet through a hot-spot?

DFirewall

Explanation

The exam marks PGP (B) as correct because PGP (Pretty Good Privacy) provides end-to-end encryption of message content, making communications unreadable to anyone intercepting them on the hotspot. However, this answer warrants a note: in practice, a VPN (C) is the standard recommendation for securing all internet traffic through a public hotspot, as it encrypts the entire tunnel between the device and the VPN server regardless of application type. PGP is primarily designed for encrypting email and file content, not general browsing traffic. If this question appears on a CompTIA A+ exam, the intended distinction is that PGP encrypts the communication payload itself rather than just the transport channel.
