Answer: B. It is hard to prove the copyright in court.
Copyright laws are made to protect the rights of authors, video makers, poets, etc. These individuals craft out contents and put them on sale. Sometimes, their works are taken illegally through free means and put on sale by individuals who are not part of the production process. The process of suing for copyright is very difficult as it consumes so much time, takes a lot of money, and is quite stressful.
