Vedclass · Answer

(B) Modulation is the process of superimposing a low-frequency message signal (baseband signal) onto a high-frequency carrier wave. This is done to ensure efficient transmission of the signal over long distances,as high-frequency waves can travel much further and require smaller antenna sizes. Therefore,the low-frequency signal is superimposed on the high-frequency carrier wave.
