Question

which is the greatest advantage of web - based applications?
secure content
accessibility
standard formatting
offline connectivity

Explanation:

Web - based applications can be accessed from any device with an internet connection, anywhere in the world. This makes them highly accessible. While security can be an issue (and is often a focus of development), it's not the greatest advantage. Standard formatting is a feature but not the most significant advantage. Offline connectivity is not a general advantage of web - based applications (though some may have limited offline functionality).

Answer:

accessibility
