Answer:
c. import quotas.
Step-by-step explanation:
Import quotas are limitations that the government imposes on the amount that can be imported from a given good or input. Import quotas have as their main reason the protection of the national industry and the employment that this industry generates. When a government sets an import quota, it understands that the national industry is at risk if too many products enter the country and compete with the national industry, which can break down and generate unemployment.
