A. The major heading from your presentation outline.
Explanation:
Microsoft PowerPoint is a presentation application package in the Microsoft office suite. It is designed with writing and graphic tools and animation effects to create an attention demanding effect on its audience.
It uses slides to present small amount of data and allow embedding and linking of other file format on the slides.
