Utility classification: which of the following is NOT a utility program?

Introduction / Context:Utilities are support programs that assist with development, maintenance, and operation—examples include editors, debuggers, file tools, and spoolers. The question asks which listed item is not a utility.

Given Data / Assumptions:

• Debugger: diagnostic tool aiding program testing.
• Editor: text/code editing tool.

Why Other Options Are Wrong:

• Debugger/Editor/Spooler: All are utilities; selecting any would contradict standard classification.
• All of the above: Would imply none are utilities, which is false.

Common Pitfalls:

• Confusing “application” with “utility”—some editors are general-purpose apps but still function as utilities.
