Correct answer: C
In the IPv4 header, fragmentation is supported using specific fields. One of them is the Fragment Offset field.
It is used to indicate the position of a fragment in the original packet
The size of this field is 13 bits
This allows proper reassembly of fragmented packets at the destination
So, the Fragment Offset field in IPv4 is always 13 bits long.
