Which statement about web apps is NOT an advantage?

• A. No need to install an app
• B. Collaboration with coworkers and friends
• C. Available anywhere with an Internet connection
• D. Designed to work on a specific operating system

Answer: (D)

Web apps are accessed via a browser, which makes them usable on many devices and operating systems without installing separate software. This cross‑platform nature is what gives them their real advantage: you can use the same web app on Windows, macOS, Linux, Android, or iOS simply through a browser with an internet connection. The statement that they are designed to work on a specific operating system is not an advantage because it would limit where the app can run, contrary to how web apps are intended to be OS‑independent. The other points—no installation needed, ability to collaborate with others, and availability anywhere with internet access—all follow from this browser‑based, cross‑platform approach.
