What consideration could be provided to help with the decision?

Northern Trail Outfitters is growing and acquiring other organizations, each with its own instance of Sales Cloud. They are debating whether to upgrade Marketing Cloud Connect to Multi-Org.

What consideration could be provided to help with the decision?
A . Shared Salesforce Data Extensions will be enabled in up to 5 business units.
B. Custom profile and subscription centers will not be required.
C. Once an account is upgraded to Multi-Org, it cannot be turned off.
D. Existing accounts cannot be upgraded to Multi-Org.

Answer: C

Explanation:

One of the considerations for upgrading Marketing Cloud Connect to Multi-Org is that once an account is upgraded to Multi-Org, it cannot be turned off. This means that the account will permanently have separate integrations for each business unit and Salesforce org, and some features may not work as expected in Multi-Org mode.
