Explanation:
A red down arrow indicates an unauthorized DHCP server. A DHCP server that is a domain controller
or a member of an Active Directory domain queries Active Directory for the list of authorized servers
(identified by IP address). If its own IP address is not in the list of authorized DHCP servers, the DHCP
Server service does not complete its startup sequence and automatically shuts down.

    And this should be the original answer:

    According to picture the DHCP service is already authorized. There are green hooks on both the IPv4 and IPv6 server icons. So the answer cannot be Authorized

    Under the Filters folder there is Allow subfolder. This is now enabled because there is no red downward-pointing arrow. When one disables the Allow filtering feature the DHCP server will be able to distribute ip addresses.
    So I think the answer is A.

    Note: Do not Enable the Allow list! Doing so will cause DCHP to operate on a “Whilelist” which require you to create an Allow List entry for every MAC address that should be given an IP address. By default, DHCP operates on a “Blacklist” which allows all MAC’s to be given an IP except for ones explicitly defined on the Deny List.
