Which parts of a presentation should be the most general?

-introduction and conclusion

-introduction and outline

-outline and conclusion

-outline and body

A. Introduction and conclusion

Explanation:

The introduction must be general and should start with an introductory statement, and then you should mention the issues you are going to discuss. However, outline and body are the main part of your presentation, and they should be professional, and of best level as well as elaborate as you can, though 70% of the time you are allotted. And when you conclude, you should again be back to being general, and you should discuss all the general ideas you discussed during the presentation, plus you should leave behind the scope for further research. The conclusion should be 10% of the time allotted to you. Thus, the answer for this question is A. or Introduction and conclusion.
