The best option in the above scenario is to: "Use proxy servers to mask Internet activities" (Option C)
Note that Proxy servers act as intermediaries between the user's device and the Internet, allowing the user to access websites and online content while hiding their IP address. This can help to protect the organization's IP address from being compromised, as the proxy server's IP address will be the one that is visible to the websites being accessed.
One must realize that using a network-based firewall, IDS, or packet-filtering firewall would not be suitable for this purpose, as these types of security measures are designed to protect the network rather than to mask the activities of individual users.
