Answer: C

Explanation:

The migration is causing the slow performance. This suggests that the on-premise Exchange server is struggling under the load of copying the mailboxes to Exchange Online. You can reduce the load on the on-premise server by reducing the maximum number of concurrent mailbox migrations. Migrating just a few mailboxes at a time will have less of a performance impact than migrating many mailboxes concurrently.
