Packets of the same session may be routed through different paths in:

Answer: B
Both TCP and UDP are transport layer protocols that rely on the underlying Network Layer (IP) for routing.
The IP layer is connectionless and packet-switched, meaning each packet (datagram) is routed independently. Due to dynamic routing, network congestion, or link changes, different packets of the same session can take different physical paths to reach the destination, regardless of whether the transport protocol is TCP or UDP.
- TCP uses sequence numbers to reorder packets that arrive out-of-order due to taking different paths.
- UDP does not guarantee order, so packets taking different paths may arrive out-of-order and are delivered to the application as-is.
Thus, packets of the same session may be routed through different paths in both TCP and UDP.
