Which resource can you give out to your audience to ensure a better understanding of the presentation?

That really depends. What audience are you tailoring to? Infographics are fun and engaging, older, more executive crowds would like graphs and numbers and charts, some would like the power point printed out in front of them with space for notes where they can write their own thoughts and questions, it depends.

The type of program is the hierarchical grid

Ibelieve the answer is: b.  use a different transition for every slide to keep the audience's attentiona. that would make it boringc. sound effects might be distracting and some people might find it annoyingi hope that : )
