Solution

The correct answer is Option 3.

Key Points

• Statement A: In connection-oriented service, the destination address is to be specified only during the setup.
  • This statement is correct because, in a connection-oriented service, a connection is first established between the sender and receiver before data is transmitted. The destination address is specified during the setup phase.
• Statement C: Flooding is a method in which every incoming packet is sent out on every outgoing line except the one by which it arrived.
  • This statement is correct. Flooding is a network routing technique where every incoming packet is sent to all outgoing lines except the one it arrived on, ensuring that packets reach their destination by multiple paths.

Additional Information

• Statement B: Packet sequencing is not guaranteed in connection-oriented service.
  • This statement is incorrect. Connection-oriented services, such as TCP (Transmission Control Protocol), guarantee packet sequencing, ensuring that packets are delivered in the correct order.
• Statement D: Presentation layer performs detection and recovery from errors in the transmitted data.
  • This statement is incorrect. Error detection and recovery are typically handled by the transport layer, not the presentation layer. The presentation layer is responsible for data translation, encryption, and compression.
