These are the choices I found on the internet:

a. make allowances for differences across industries and between firms.

b. set standards that are applicable to all situations and does not recognize unique circumstances.

c. set a minimum requirement and then allows the firm to determine the most efficient method for achieving this requirement.

d. determine the most efficient method for different industries.

It would be letter B - set standards that are applicable to all situations and does not recognize unique circumstances. The command-and-control regulation is inflexible. It usually demands the same standard for all polluters. This means that it draws no distinctions between firms.
