Final answer:
Dean should choose Company A because it offers a collision damage waiver without a loss damage waiver.
Step-by-step explanation:
Dean should choose Company A because it offers a collision damage waiver without a loss damage waiver. A collision damage waiver is an optional coverage that protects a renter against any damage to the rental car in the event of a collision. On the other hand, a loss damage waiver protects the renter against any loss or damage to the rental car, including theft, vandalism, and accidents. Since Dean only wants the collision damage waiver, Company A is the best option.
