Answer:
© is the copyright symbol
Explanation:
The copyright symbol is usually found at the end of a published material. This symbol indicates that a person is the owner of a publication. This makes others take permission for use from the owner.
The 1952 Universal Copyright Convention states that the copyright notification must also carry the name of the owner and the year of publication.
The copyright notification is usually placed on the tittle page, back page or the last page after the content page. Website owners can place theirs on every page as they dim fit. 
An example of a copyright notification is © 2020 Peter Pan
