You Work as a Marketing Coordinator for Gillespie Homes, a Construction

You work as a marketing coordinator for Gillespie Homes, a construction firm in Calgary. Your job duties include delivering oral presentations for a variety of different purposes to many different audiences. One of your current tasks is to prepare a presentation for the company’s sales team to outline the projected time frame and marketing strategies your department has developed to sell homes the company has built in a new subdivision. The members of your sales team have made it clear that they consider the material you will present to them dull and irrelevant. They have found these presentations to be repetitious and boring in the past. However, your boss insists that they need the information and that attendance is mandatory.
You also need to make a presentation to small groups of potential suppliers of products and services. You have been asked to provide additional information and explain how to submit a proposal using the company’s new online proposal form. You have heard from several of these suppliers already who are frustrated and hostile about the new form, which they consider unnecessarily long, detailed, and confusing.
-What would be the most effective way to conclude your presentation to Gillespie's suppliers?

A) Introduce and develop one important point that you didn't mention earlier.
B) Summarize the main points in the process of completing and submitting an online proposal.
C) Remind the audience that you have a great deal of experience dealing with proposals for goods and services.
D) End by saying "I guess that's about all I have to say."
