Answer:
Option b is the correct answer for the above question.
Step-by-step explanation:

- This policy asked some information from the user and block that user who have no knowledge about that information.
- No user can access the document either it has a good position or rank. There is a need to verify the knowledge in front of the site.
- The above question Asked about the policy which is used to give access to the right user. This policy is known as the need to know. so the b option is correct while the other is not because:-
- Option 'a' states about least privilege which is another security mechanism.
- Option c states about confidentiality which comes under the need to know.
- Option d states about access control which is not the correct answer.
