AI Explanation

The correct answer is B. To initiate a station-to-station call over a sound-powered telephone circuit, you need to: 1. Select the station you wish to call using the rotary selector switch. 2. Turn the hand-crank a few revolutions to generate the necessary electrical power for the call. 3. Depress the button on the handset to connect the call. 4. Listen for your party to answer the call. This procedure is correct because sound-powered telephones rely on the mechanical energy generated by turning the hand-crank to provide the power for the call, rather than using external electrical power sources. The other options are incorrect because they either skip the hand-crank step (A and D) or select the wrong station (C).
