hich of the following statements is true regarding the “pseudo-header” used in TCP and UDP?Question 2AnswerIt is transmitted together with the transport layer packetIt is the same as the transport layer header to improve reliabilityIt has a field for multiplexing/ demultiplexing so that packets are delivered to the correct Application layer.It is included in checksum calculations, making delivery of the packet to the wrong host very unlikely

The true statement regarding the “pseudo-header” used in TCP and UDP is: "It is included in checksum calculations, making delivery of the packet to the wrong host very unlikely."

Here's why:

1. The pseudo-header is not transmitted together with the transport layer packet. It is used only for the calculation of the checksum at the sender side and then discarded.

2. The pseudo-header is not the same as the transport layer header. It is a part of the transport layer used for checksum calculation to improve reliability.

3. The pseudo-header does not have a field for multiplexing/demultiplexing. The multiplexing/demultiplexing is done based on the port numbers in the transport layer header, not the pseudo-header.

4. The pseudo-header is included in checksum calculations. This is done to ensure that the packet is delivered to the correct host. If the packet is delivered to the wrong host, the checksum calculation at the receiver side will fail, making the delivery of the packet to the wrong host very unlikely.
