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.

A light switch is digital, it's either on or off. A dimmer switch is analog. You can adjust the amount of light by sliding the slider or turning the knob, depending on which type of dimmer switch you have.

Thermocouple is an active transducer not a device, rest all options are valid for any device, a device is not self powered.
Current flow in a circuit is Charge per unit time, (I) , its not a device.

Thermocouple is a device and so thermocouple directly detects temperature and give output in the form of some e.m.f. in the form of 0 or 1.

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

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

It's a digital device because it records or displays any sort of data in digital format, i.e in the form of 0&1.

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

Digital wave form high and low and switch operates on and off it means high and low because this is digital device.
