Which of the following choices is a goal of sustainable practices? a. they focus on using resources for maximum productivity. b. they focus on using resources that can disappear if overused. c. they focus on using resources that can be renewed. d. they focus on using resources for maximum profit.

The answer should be C, they focus on using resources that can be renewed.

In order to become sustainable, industries have to maintain a balance between economic, social and environment. If they focus on only one or two aspects, they may not be able to become sustainable.

Economic aspects may include diversifying the ecomic structure; social aspects may include setting a minimum wage level for workers, providing a good working environment; and environment may include using renewable resources in production or handling their own pollutants.

Therefore, if they only focus on economic aspects such as maximizing productivity or profit, they may cause a lot of damage on the environment or even cause problems to the workers. So, the best answer is C. It also focuses on the environment, so that resources may be less likely to run out.
