Which of the following is NOT a part of desktop publishing?

The correct choice identifies video editing as an activity that does not fall under the umbrella of desktop publishing. Desktop publishing primarily focuses on the creation and layout of visual documents that combine text and graphics for print or digital distribution. This includes tasks such as graphic design layouts, arranging text for reports, and using word processing for text editing.

Video editing, however, is a different field that involves manipulating and arranging video footage, adding effects, audio, and transitions. While both desktop publishing and video editing involve design elements, they use different tools and processes tailored to their specific mediums. Thus, video editing is clearly not a part of desktop publishing.
