Universal Containers wants to ensure that users complete the standard Industry field when creating a new account record. To address this concern, the administrator set the Industry field as required. However, some users are still able to create a new account record without completing the Industry field.
What should an administrator do to troubleshoot the issue?

a. Verify the Industry field is set as required on all the account page layouts assigned to the users’ profiles.
b. Verify the users have the "Modify All Data" permission for accounts on their profiles.
c. Verify the users have the "Edit" permission for accounts on their profiles.
d. Verify the field-level security for the Industry field is not set to "Read Only" on the users’ profiles.
