Answer: (iv) CTS is made low at first (false statement)

Explanation: In RTS/CTS handshake, RTS (Request To Send) is asserted low first by the transmitter/receiver requesting to send, then the other side asserts CTS (Clear To Send) low to grant permission. Saying "CTS is made low at first" reverses the sequence, so it is the false statement. RTS originates at DTE, CTS is response.
