Permission, rights & Policies!

The Difference between the following three terms are:

• Permission:- The task and features that a user can perform and/or access respectively.
• Rights: They are the ability Permission and specific tasks assigned to customized users.
• Policy: It is a document that a user must agree upon to follow, so as to give the access to the system and the network

Well, considering the difference of the three, this was the solution...

Hope this works!
