The group hierarchy for the programmers of your company is as follows: the parent group is called Programmers. The Programmers group has three subgroups, Database, Web Design and Accounting. The Accounting group previously was the only Programming group to have access to the Billing folder. Since the Accounting programmers no longer need that access and none of the other programmers do either, you've decided to deny all access to the Billing folder to the parent Programmers group. You notice that Pamela, who is in the Accounting group, can still access the Billing folder. What should you do first?

a. Disable Pamela's account immediately.

b. Check other Accounting accounts to see if the permissions were inherited properly.

c. Deny access to the Billing folder specifically for Pamela.

d. Deny access to the Billing folder for the Accounting group.
