Which tool is described as a free software that defends against traffic analysis by providing an open network?

• A. Orbot
• B. Tor
• C. Psiphon
• D. OpenDoor

Answer: (A)

The idea being tested is anonymous communication by using a network designed to resist traffic analysis. Tor achieves this by routing your traffic through multiple relays, layering encryption so observers can’t easily deduce who you are or what you’re accessing. Orbot fits as the described tool because it is the free, open-source Android client that acts as a Tor proxy. By running Orbot, your mobile apps can send traffic through the Tor network, leveraging its onion routing to shield your activity from network observers. This combination—a free, open-source client on a device that connects you to the Tor network—best matches the description. Tor itself is the open network that provides the anonymity, but the question highlights a tool that makes that network accessible on a device. Psiphon focuses more on censorship circumvention using VPN/SSH techniques, not specifically on traffic-analysis defense via an open network. OpenDoor is not a standard tool associated with Tor or traffic analysis protection.
