Show Hint
- in region (III)
- both in region (I) and (III)
- in region (II)
- in region (I)
The Correct Option is B
Solution and Explanation
Step 1: Understand the working of a transistor as a switch.
In the active region (III) of the transistor, it behaves like a switch, and in the cutoff region (I), it is off.
Step 2: Conclusion.
For a transistor to act as a switch, it needs to operate in both the cutoff (I) and saturation (III) regions. "
Final Answer: \[ \boxed{\text{both in region (I) and (III)}} \]
