Answer: C

Explanation:

In this question, we are migrating the mailboxes over a period of time (minimum of four weeks). During the migration period, we will have a hybrid deployment where the Exchange environment exists both on-premise and online.

To meet the requirements of the question, we can use a remote move migration.

A remote move migration is used to migrate on-premises Exchange mailboxes to Exchange Online in an Exchange hybrid deployment. You must have an Exchange hybrid deployment to use a remote move migration. With a hybrid deployment, you get the following capabilities:

Even if you plan to permanently move your on-premises email organization to Exchange Online and Office 365 over a longer period of time, you can take advantage of these hybrid deployment features during the transition.
