In the diagram below (not to scale), each of the loudspeakers emits a continuous sound of the same frequency. The whole system is kept in air. A microphone moved along the line

(A) Decreasing the frequency of the sound emitted by the loudspeakers
(B) Increasing the frequency of the sound emitted by the loudspeakers
(C) Decreasing the separation of the loudspeakers
(D) Increasing the distance of the loudspeakers from the line .
