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.

Options A, C & D denote devices showing different outputs over different inputs. The output here is analogous to the input. Hence, these are analog devices.

Switch is only follow the ON AND OFF. So it describe the digital system.

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.

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.
