Failover Priority dictates order of migration away from a failing (or forced‐over) WLC. Fallback behavior, on the other hand, is governed by the AP Fallback feature and whether the AP even knows how to reach its primary.

If AP Fallback is not enabled on all WLCs, only the APs connected to WLCs with this feature enabled will return to their primary WLC once it recovers.

I chose C and E. The secondary WLC would have to have been configured correctly or the APs would have never joined the secondary WLC after failover occurred. Also, the AP Fallback has to be enabled because most of the APs did fall back and some didn't. If it wasn't enabled, all APs would not fallback to the primary AP. Lastly, I'm totally unsure of this but I believe the DHCP Option 43 information doesn't supply the APs with failover information. So that only leaves us with two answers. I fully believe E is one of the answers. I'm not totally sold on C but I don't have any other choice.
