A word processor can be used to

A word processor is application software designed for creating and handling text documents. Its core functions cover the whole life cycle of a document, from first creating it to producing a final copy.

Users can write new text into a document, go back and edit that text by inserting, deleting, or reformatting words and paragraphs, and then print the finished document onto paper. These are not separate, competing capabilities; they are all standard, everyday functions built into any word processor such as Microsoft Word.

Because writing, editing, and printing are all genuine and commonly used features of a word processor, the complete and accurate answer covers all three rather than singling out just one.

Exam takeaway: when a question lists several correct, non-conflicting capabilities of the same software and one choice claims all of these are true, check whether every listed capability genuinely holds before ruling it out.
