Answer:
D) copyright law.
Step-by-step explanation:
Copyright law can be defined as a set of formal rules granted by a government to protect an intellectual property by giving the owner an exclusive right to use while preventing any unauthorized access, use or duplication by others.
Hence, when anyone downloads music tracks owned by record companies without paying for them, it is an example of a violation of copyright law.
The copyright law which protects the sharing and downloading rights of music is known as the Digital Millennium Copyright Act (DMCA).
