Answer: D
4GLs are usually not suitable for data intensive operations.
Instead, they are used mainly for graphic user interface
(GUI) design or as simple query/report generators.
Screen/report design facilities are one of the main
advantages of 4GLs, and 4GLs have simple programming
language subsets. Portability is also one of the main
advantages of 4GLs.
