Which of these is a good?

A fancy hair cut

An oil change with 20 point inspection

A rusted out car

A $4.00 car wash

Explanation:

Option A: A fancy hair cut option is given but it is not associated with any of the price. So we cannot say it is good or worth for the money.  

Option B: It seems to be valid. But when we consider all the given options, there are better options than this.

Option C: Rusted means a brown layer formed on the body of the car. So we cannot say it is good. So this option too is invalid.

Option D: Normally car wash costs $10. It is worth to do a complete car wash with $4.00. This option is the best choice.
