A menu-driven system A. can be used only by computer professionals B. is required only for on-line systems C. increases the operator’s work D. presents options and allows the user to make selections E. None of the above

The correct answer is: D. presents options and allows the user to make selections.

A menu-driven system is a type of user interface that presents the user with a list of options, from which the user can select one. This is in contrast to a command-line interface, where the user must type in commands to perform tasks. Menu-driven systems are often used in applications that are designed for users who are not familiar with computers, such as word processors and spreadsheets.

Here is a brief explanation of each option:

• A. can be used only by computer professionals. This is incorrect because menu-driven systems can be used by anyone, regardless of their level of computer expertise.
• B. is required only for on-line systems. This is incorrect because menu-driven systems can be used for both on-line and off-line systems.
• C. increases the operator’s work. This is incorrect because menu-driven systems can actually reduce the amount of work that the operator has to do, by making it easier to select the desired option.
• E. None of the above. This is the correct answer because it is the only option that is not contradicted by the definition of a menu-driven system.
