A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -TCP ensures that each segment that is sent by the source arrives at the destination. Provides Same-Order Delivery-Because networks may provide multiple routes that can have different transmission rates, data can arrive in the wrong order.

Detailed explanation-2: -TCP confirms that a packet has reached its destination by establishing an end-to-end connection between sending and receiving hosts. TCP is therefore considered a “reliable, connection-oriented” protocol.

Detailed explanation-3: -A connection-oriented transport layer protocol, such as TCP, may be based on a connectionless network layer protocol (such as IP), but still achieves in-order delivery of a byte-stream, by means of segment sequence numbering on the sender side, packet buffering and data packet reordering on the receiver side.
