Here saturation region means max range and cutoff region means minimum voltage. So in digital sys we are using 1 and 0 only.

In saturation region transistor acts as closed switch and in cut off region it acts as open switch. In digital circuits o/p can be 0 or 1. So when in saturation region means closed switch it gives output 1 and in cut off region means open switch it gives o/p 0.

While transistor has to be used as an amplifier then it is operated in active region.

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.

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.

For amplifying purpose we use transistor in active region and saturation or cutoff regions used in digital electronic circuits.

Where these tranisitors are used in real time fields ?

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.

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).

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.
