Recommendations for a successful pitch include all of these except:

a. stand behind a podium

b. maintain eye contact

c. use colorful visual aids

d. do a live demonstration of the product or service

e. all of these choices are recommended for a successful pitch

The answer is letter a, it is because when doing a successful pitch or in order to achieve one, a person is not even required to stand behind a podium as it does not necessarily need or refer to a specific place to stand on when delivering a pitch but it is more important to show the product or service to attract the consumers.
