Answer:
c) the company uses small amounts of copyrighted material
Step-by-step explanation:
According to the fair use doctrine, the government of the US permits uses of the copyrighted material if the amount of copyrighted material is in very small amount and also does not constitutes to unfair advantage over the company which has copyrighted the material formula. Whereas on the other hand, the employer will face legal action if the employee faces any injury at work and this is well addressed in employees right act.
Furthermore, age descrimination is a illegal act so the company will again face legal actions in this case too.
