Explanation:

- Washing one’s own clothes: This involves using water and detergent, but it does not result in permanent pollution. Detergents can contribute to water pollution if not biodegradable, yet it’s not labeled as permanent pollution.

- Cutting one’s own hair: Hair itself is biodegradable and does not contribute to pollution. Thus, this activity does not cause permanent pollution.

- Cleaning one’s own utensils: This activity can involve the use of soaps and water but, similarly to clothes washing, does not result in permanent pollution. Soaps or detergents washed away can be treated in sewage systems.

- None of the above: Given the context, none of these activities lead to permanent pollution on their own. Therefore, this option seems accurate.

None of the above
