    Answer:

    The answer is “False

    Explanation:

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

    • 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.
