Answer: B. The purchasing incentive customers appreciate most is a price drop.
A is not an opinion since the bottles can very well be sold at the prices and someone's own feelings can not change the price of a bottle.
B is an opinion
C is not an opinion, because once again someone's feelings can not change the fact that Mr. Tansky and Mr. Marcus are president and CEO, respectively.
D is not an opinion, because it is proven that companies have sales so that more customers will want to shop there.
All of this leaves us with the choice, B. It is an opinion, because it is not proven with facts and there is flexibility. A customer may enjoy other purchasing incentives, such as Buy One Get One Free or Coupons , so this reason B is an opinion and our correct answer.
I hope this helps & Good Luck <3!!!!
