Which kind of called

The closing of a presentation should end with either a recap of what your presentation discussed or with a simple conclusion to put an end to your thoughts. These two options would help your presentation flow together fluently. More than likely, you will get an A if you formed the presentation in an organized manner and put correct and accurate information into the body of your presentation.
Hopefully this helps :)
