Final answer:
A potential punishment given to a producer found guilty of an unfair method of competition is suspension of license.
Step-by-step explanation:
A potential punishment given to a producer found guilty of an unfair method of competition is suspension of license.
When a producer is found guilty of engaging in unfair competition practices such as price fixing or collusion, their license to operate may be suspended by the relevant regulatory authority.
This suspension prevents the producer from continuing to engage in the unfair practices and serves as a deterrent to others who may consider engaging in similar actions.
