Final answer:
The most useful program to keep Kim's private information safe while she works on public Wi-Fi is a VPN.
Step-by-step explanation:
The correct answer is option VPN. A Virtual Private Network (VPN) is a program that can help keep Kim's private information safe while she works on public Wi-Fi.
When Kim connects to a VPN, her internet traffic is encrypted and routed through a secure server, masking her IP address and making it difficult for anyone to intercept or access her data.
The correct answer is that a program most useful in keeping Kim's private information, including her IP address safe while she works, is a Virtual Private Network (VPN).
While working on public Wi-Fi at airport hotels or other locations when traveling, a VPN encrypts her internet connection, which helps protect her data from being intercepted by others.
It also masks her IP address, making her online actions virtually untraceable and giving her the ability to appear as if she's working from a different location to ensure her privacy and security.
