Final answer:
The limit on car engine particulates is an example of command-and-control regulation, which prescribes specific pollution limits and technologies for emissions reduction.
Step-by-step explanation:
The law that sets a limit on how many particulates a car engine is allowed to produce is an example of command-and-control regulation. This type of policy is characterized by the government specifying allowable quantities of pollution and may also dictate which pollution-control technologies must be used by companies. The goals of such regulations are to reduce the social costs of pollution and protect the environment by imposing direct limitations on emissions and sometimes by requiring the installation of specific emission reduction technologies.
The law that sets a limit on how many particulates a car engine is allowed to produce is an example of command-and-control regulation. Command-and-control regulation specifies the allowable quantities of pollution and the pollution-control technologies companies must use. It requires companies to increase their costs by installing anti-pollution equipment, thereby accounting for the social costs of pollution.
the correct option is b. Command and control
