What should you do?

Your company has an OU that contains your sales team and an OU that contains your market research team. The sales team is often a target of mass email from legitimate senders, which is distracting to their job duties. The market research team also receives that email content, but they want it because it often contains interesting market analysis or competitive intelligence. Constant Contact is often used as the source of these messages. Your company also uses Constant Contact for your own mass email marketing. You need to set email controls at the Sales OU without affecting your own outgoing email or the market research OU.

What should you do?
A . Create a blocked senders list as the Sales OU that contains the mass email sender addresses, but bypass this setting for Constant Contact emails.
B . Create a blocked senders list at the root level, and then an approved senders list at the Market Research OU, both containing the mass email sender addresses.
C . Create a blocked senders list at the Sales OU that contains the mass email sender addresses.
D . Create an approved senders list at the Market Research OU that contains the mass email sender addresses.
