The general manager has asked the coordinators to promote a line of products that hasn't been selling very well. Chelsi observes that those products are all on the bottom shelf of the display and thinks that product placement could be the issue. Which of the following research questions might help Chelsi investigate her theory that product placement is contributing to low product sales? A) Will the product sell better if the coordinators give customers coupons for 10% off? B) Will the product sell better if it's displayed on a more visible shelf for two weeks? C) Will the product sell better if the stylists discuss the products occasionally? O D) Will the product sell better if all the other products are removed from the display? SUBMIT
