As the Chief Sales and Marketing Officer for Kia Motors

As the chief sales and marketing officer for Kia Motors, it's up to you to set pricing tactics in what is an established competitive pricing environment. Right now, you're looking at your firm's line-up of four different gas-powered sedans, each of which is distinctly different from the others, although they all tend to look fairly similar. Which tactic is the best approach for pricing Kia sedans?

A) Suggest they are premium products by pricing them slightly higher than competitors
B) Use odd pricing to make consumers think they're getting a better bargain with Kia
C) Set a very low price point for all Optimas, the low-end model, to lure consumers away from other brands
D) Differentiate them by categorizing them into price tiers ranging from $22,500 to $49,900
