Your company’s Exchange organization contains only Exchange Server 2003 servers.
The company has a department named Sales and an organizational unit (OU) named Sales Department.
You need to ensure that all employees in the Sales department are members of a distribution group named Sales. The solution must automatically update the Sales group membership when new sales employees are hired.
What should you do?

A.
Create and mail-enable a universal distribution group named Sales. Add the group name to the Managed By tab in the Sales Department OU properties.

B.
Create and mail-enable a universal query-based distribution group named Sales. In the properties of the group, specify a custom LDAP filter that includes the sales employees.

C.
Create and mail-enable a universal security group named Sales. Automate a dsquery user command to identify Sales employees and run dsadd group to update the Sales group membership.

D.
Create and mail-enable a universal distribution group named Sales Users. From Active Directory Users and Computers, create a saved query that identifies the sales employees. Add new sales employees to the query.
