Final answer:
The correct option for narrating a stand-alone presentation is 'Record Narration', allowing the addition of a spoken explanation to accompany the slides.
Step-by-step explanation:
To narrate a presentation for stand-alone delivery, a developer can select the Record Narration option. This feature is commonly found in presentation software like PowerPoint and enables the user to add an audio track to the presentation where they can verbally explain or elaborate on the content of the slides. Utilizing Record Narration helps create a more engaging and self-sufficient presentation, particularly for viewers who may be accessing the content independently, such as through a video-sharing platform like Yo uTube or an educational website.
