Answer:
A. true
Step-by-step explanation:
Copyright is a legal right which is exclusive in nature. It is the right of the owner to use his creative work which may be in the form of art, music, buildings, photographs, literature, etc. in a way he means to use. It gives ownership of the piece to the one who creates it.
Using a copyright piece of others without the owner's prior permission is an offence and is against the law.
