Answer 1

The best example of cost-benefit impact among the options provided is D: buying a reusable water bottle that is expensive but helps the environment.

This choice highlights a cost (the higher price of the reusable bottle) and the benefit (environmental impact), which illustrates the concept of weighing costs against benefits. Options A, B, and C do not clearly present a situation where significant costs are weighed against significant benefits in the same manner.
