Which one of the following is not a client server application?

Consider the following statements about the timeout value used in TCP. i. The timeout value is set to the RTT (Round Trip Time) measured during TCP connection establishment for the entire duration of the connection. ii. Appropriate RTT estimation algorithm is used to set the timeout value of a TCP connection. iii. Timeout value is set to twice the propagation delay from the sender to the receiver. Which of the following choices hold?

• (i) is false, but (ii) and (iii) are true
• (i) and (iii) are false, but (ii) is title
• (i) and (ii) are false, but (iii) is true
• (i), (ii) and (iii) are false
