Correct Answer:
B. F5
In Microsoft PowerPoint, specific function keys are assigned to control slideshow presentations efficiently. The question asks for the key that starts the slideshow from the very first slide.
- F5 is the correct answer. Pressing the F5 key initiates the presentation from the beginning, regardless of which slide is currently selected in editing view. This is a fundamental shortcut for starting a presentation.
- F1 is incorrect; this key typically opens the Help window in most Microsoft Office applications, including PowerPoint.
- Shift + F5 is also incorrect. While it starts a slideshow, it begins from the *current* slide that is selected in the editing view, not necessarily the first slide.
- F7 is incorrect; this key is commonly used to perform a spell check in Microsoft Office programs like PowerPoint, Word, and Excel.
Understanding these shortcuts enhances productivity when working with presentations.
