Because it work in only two function ON /OFF.
LIKE DIGITAL NO. SYSTEM 0 OR 1.

If it works oly on 0's and 1's then its digital and not analog.

It is not gate in the on /off position.

Light switch is digital device because it has only two state ON/OFF.

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

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