User a Is a Basic License Holder

User A is a Basic License holder. User B is a Business License holder. These two users, along with many additional users, are in the same organizational unit at the same company. When User A attempts to access Drive, they receive the following error: "We are sorry, but you do not have access to Google Docs Editors. Please contact your Organization Administrator for access." User B is not presented with the same error and accesses the service without issues. How do you provide access to Drive for User A?

A) Select User A in the Directory, and under the Apps section, check whether Drive and Docs is disabled. If so, enable it in the User record.
B) In Apps > G Suite > Drive and Docs, select the organizational unit the users are in and enable Drive for the organizational unit.
C) In Apps > G Suite, determine the Group that has Drive and Docs enabled as a service. Add User A to this group.
D) Select User A in the Directory, and under the Licenses section, change their license from Basic to Business to add the Drive and Docs service.
