The answer is "False"

Explanation:

In the given question one option is missing, that's why its explanation can be described as follows:

According to wave nature, it is the DC output, which is also known as the essence of alternating current (AC). To convert AC to DC, we must want to see something called a rectifier. Its frequency DC is not a continuous but perhaps a rippling pulse that is in the way of a fixed value, that's why all the given choices were wrong.
