Question

Which is the best practice for placing graphics on a slide?

Answer 1

All the choices depend on the slide and the last one is a must. the first one should be for the introduction and conclusion and the second one should be used to make ideas conveyed in the presentation easier to understand.

Answer 2

I believe that the answer depends on the nature of presentation; is it serious or funny, is it for a project, job or friends, etc. I would avoid option C in most cases (two pictures is ok, more is not ok).
