Best answer
Right option is (a) Feet per minute

Explanation: The anemometer measures in feet per minute, or FPM. The rotation is sensed by a magnetic or optical sensor that converts the signal to FPM measurement. An arrow on the vane head identifies the direction the airflow must travel through the vane to obtain proper measurements.
