Q. In TCP, the path

(A) To be followed depends on the length of message
(B) Up to destination is allocated before the transmission of message begins
(C) Up to next intermediate node is allocated before the transmission of message begins
(D) None of the above

✅ Correct Answer: (D) None of the above

Explanation:

In TCP (Transmission Control Protocol):

TCP is a connection-oriented protocol, but it works on top of IP (Internet Protocol), which is connectionless.
This means:
- The entire path is not fixed before the message transmission.
- Each packet may take a different route to the destination depending on network conditions.
- TCP ensures reliable delivery by reordering packets and handling retransmissions, but it does not control the path.

Why other options are incorrect:

(A): Path selection is not based on message length.
(B): This is true for circuit-switched networks (like old telephone systems), not TCP/IP.
(C): Intermediate node selection isn't pre-allocated in TCP/IP.

So, (D) None of the above is correct.
