You have two groups of managers that need to hold Meet-Me conferences.
You want each group to have access to a range of 10 Meet-Me numbers.
What are the two best ways to accomplish this?

A.	Create two different partitions and add both groups of 10 Meet-Me conference numbers to the partitions.
B.	Ensure that the 10 Meet-Me conference numbers overlap with existing ad hoc conferencing numbers.
C.	Create two different groups of Meet-Me conference numbers, add them to the partition, and add the partition to the two manager groups to provide limited access.
D.	Create a different partition for each group of managers and assign a set of 10 Meet-Me conference numbers to each.
E.	Create two groups of 10 Meet-Me conference numbers that do not overlap with any other number in the numbering plan.
