Grant Visited a Local Medical Office and Gave a Hands-On

Grant visited a local medical office and gave a hands-on demonstration to the administrative assistants of a software product he was selling that streamlined medical coding for insurance billing. The office assistants were excited at the prospect of using the software, and the price was affordable, but Grant did not make a sale. Which of the following reasons most likely explains the failure of this presentation?

A) The audience did not include the managers and technology decision makers who choose which software the office will use.
B) Medical billing software is not the type of product that the members of this audience would be interested in.
C) He gave a hands-on demonstration of the product when the audience members were not kinesthetic learners.
D) His presentation was too formal for the small group of administrative assistants who attended the product demonstration.
E) The audience members did not have the background knowledge and education to understand what Grant was presenting.
