What is the maximum bandwidth at which a IP host can send 700 bytes of packets without having the 16 bit Datagram identification field wrap around within 100 seconds?

(a) 3.67 Mbps

(b) 4.84 Mbps

(c) 1.63 Mbps

(d) 2.8 Mbps

Please read below...

As I know some concepts:

TCP is Byte stream protocol ( Every byte counted)

IP is packet stream protocol (Every packet counted)

Identification field(16 bits) in datagram is used identify every datagram uniquely and also in fragmentation..

Wrap around time : simply after how much time we are going use same sequence number...

Now my doubt is

1)what happen if we send packet without identification number??

2)Is it possible to send datagram without identification number??

AND PLEASE CORRECT MY CONCEPT IF I AM WRONG...thanks in advance
