in my eyes 1) would be correct as per RFC 3330
224.0.0.0/4 - This block, formerly known as the Class D address space,
is allocated for use in IPv4 multicast address assignments. The IANA
guidelines for assignments from this space are described in [RFC3171].
240.0.0.0/4 - This block, formerly known as the Class E address space,
is reserved. The "limited broadcast" destination address 255.255.255.255
should never be forwarded outside the (sub-)net of the source. The
remainder of this space is reserved for future use. [RFC1700, page 4]
