When beginning your presentation to the prospective customer, the most effective way to convince them about your product/service is to:
Find out what is important to them by asking probing questions.
Tell them about your company history and why your customers enjoy working with you.
Talk about why your product / service is better than your competition’s.
Tell them you can beat any price they can find.
That is Correct, Answer is A
The Wisdom Behind The Answer
Until you know what's important to the customer and until you have asked them revealing questions, all of your sales presentation is basically meaningless, whether you are telling them about your history, product or price. The sales presentation should focus around the customer, not the sales pitch.
