Unable to interpret?
Data | sender address | destination address

A - 2 (we can not use DBA in sender address)

B - 3 (Limited broadcast address 255.255.255.255)

C - 1 (unicast Packet within the network)
How can you say 240.255.255.255 is the DBA ?

11110000. 11111111 . 11111111 . 11111111

Now i agree that last bits are 1 but it is not required that these are host bits.Please check
Ya true, didn't notice  its class E address... So these address are reserved... And we don't practically use them..255.255.255.255 is an exception here, which we use as limited broadcast address.
