As we switch means either on or off It doesn't has any continuous functioning like analog signals so It is digital device.

Analog devices are like continuous wave form nature.
But digital signals have only two states that's why it is digital device.

Analog device contains only 2 inputs right 1 and 0, then how does a microphone be a analog device.

Analog is continues in nature. Switch operates only in 0's & 1's. So it is in digital form.

When we give input it indicate 1 by glowing and indicate zero by remaining off.

Switch play it's role in two state that is ON/OFF(1/0). It is not a analog device.

Analog device means works like switch.

Option D is analog device because it simply just convert the energy from one wave to another so it is analog device.

Options A, C & D denote devices showing different outputs over different inputs. The output here is analoguous to the input. Hence, these are analog devices.
However, for a light switch, if it is off, the output is 0(light off) for any voltage extremes. Similarly, if it is on, output is 1(light on). As output fluctuates between 0 & 1, switch is a digital device here. Hope that helps.

It work like ON and OFF like digital format.
