Why each option

UDP offers lower overhead than TCP due to its connectionless nature, and it allows applications to use checksums for data integrity verification.

AUDP traffic has lower overhead than TCP trafficCorrect

UDP is a connectionless protocol that does not establish a session, perform flow control, or acknowledge receipt, resulting in significantly less header overhead compared to TCP.

BUDP provides a built-in recovery mechanism to retransmit lost packets.

UDP is a connectionless protocol and does not provide any built-in mechanisms for retransmission or recovery of lost packets; this functionality must be handled by the application layer.

CThe CTL field in the UDP packet header enables a three-way handshake to establish the

UDP headers do not contain a CTL field, and UDP does not perform a three-way handshake to establish a connection, as it is a connectionless protocol.

DUDP maintains the connection state to provide more stable connections than TCP.

UDP does not maintain connection state; it is a connectionless protocol, meaning each packet is treated independently without prior setup or teardown, thus not providing connection stability like TCP.

EThe application can use checksums to verify the integrity of application dataCorrect

While UDP itself does not guarantee delivery, its header includes a checksum field that applications can utilize to verify the integrity of the data received, ensuring that it has not been corrupted during transit.
