Saturation region of transistor is maxim. Current flows (collector base, emitter base current in forward direction, but collector current not constant with rapidly inc. Ck. This is resign behind that.

Basically the digital circuits operate only binory digits (i.e 0 and 1) , when ever this is opearates in bjt saturation region (the swith is on) , &the cut off region (the switch is off).

Generally Digital circuits require swithcing elements and that's why tarnsistors whenever used in digital circuits, always are operated in saturation (ON) and cut-off (OFF) mode.

The whole digital world considers only two states. That is on and off/ 1 and 0. So now the transistors saturation and cut-offs can be considered as on and off respectively.

Digital circuit requre swiching element (ON&OFF) , that why transistor whenever used in digital circuit always operate in saturation (ON) & cut off (off) in region.

In digital cirucuit transistor are used as a switch.
Transistor used as a switch when they are either operate in the saturarion or in cutoff mode so answer is option c.

In digital circuit We works with either HIGH or LOW, so when transistor is in saturation (Vce i.e. max) it is on high voltage, and low voltage when it is in Cutoff (0V).

Why we are discuss, I don't know.
Simply For amplifying purpose we use transistor in active region and saturation or cutoff regions used in digital electronic circuits.

Saturation mens input voltage is max and out is minimum so it can consider as zero and in cutoff region input is zer hence max output. So can consider as 1.

Generally the digital circuits have two operating points 0 and 1. So when transistor operates in saturation region it can be switched on and off.
