In CMOS inverter, transistor is a switch having . . . . . . . . A. Infinite on resistance B. Finite off resistance C. Buffer D. Infinite off resistance

The correct answer is: B. Finite off resistance

In a CMOS inverter, the transistor is a switch that has a finite off resistance. This means that when the transistor is turned off, there is still a small amount of current that flows through it. This current is called the leakage current, and it can cause problems in some circuits.

The other options are incorrect because:

• Option A: Infinite on resistance is not possible. A transistor cannot have infinite resistance, because then it would not be able to conduct any current.
• Option C: A buffer is a circuit that isolates one part of a circuit from another. It does not have anything to do with the resistance of a transistor.
• Option D: Infinite off resistance is not possible. A transistor cannot have infinite resistance, because then it would not
