* Presentation aids can be used throughout the speech but it should be used for essential points so as to to tire or bore the audience.

* Ensure presentation still works without the presentation aids in case of technical problems or if any problem arises at all.

* While explaining the aids, focus should be on the audience and not the presentation aids itself.

* Practice should be done with the presentation aids in advance so as to avoid any error while presenting.

Therefore, options A, B should be done when using presentation aids.
