The correct choice is (a) Wind socks

For explanation: Wind sock is a very basic device that measure wind direction and provide a rough idea of the wind’s intensity. A wind sock is a tubular piece of fabric or thin, flexible fabric attached to a pole. When there is no wind, the fabric hangs vertically from the attached pole.
