Anti-pollution policies can be over-aggressively designed and implemented, resulting in: ) the social costs of pollution reduction becoming less than the benefits. b) too few resources being devoted toward reducing pollution. c) the social benefits of pollution reduction becoming zero d) the social costs of pollution reduction becoming greater than the benefits.

D) the social costs of pollution reduction becoming greater than the benefits.

Explanation:

If anti-pollution policies are over-aggressive, that means that they are extremely strict and usually too expensive to comply with. For example, France plans to ban all internal combustion cars by 2030. That means that only electric cars or hydrogen powered cars will be sold in France starting 2030.

This type of policy is extremely aggressive and really hard to achieve successfully since electric cars or hydrogen powered cars are not cheap. Therefore the social costs of implementing that policy will probably be greater than the social benefits generated by the policy. In Europe cheap cars start around 10,000€ while electric cars start over 30,000€ (if you take away government subsidies the price rises).
