The operating point is also called the ___________

The correct answer is: B. Quiescent point.

The quiescent point (Q-point) is the steady-state operating point of a transistor amplifier. It is the point at which the transistor is biased so that it operates in the linear region. The Q-point is determined by the values of the bias resistors and the input signal.

The cut-off point is the point at which the transistor is turned off. The saturation point is the point at which the transistor is turned on.

Here is a more detailed explanation of each option:

• Cut-off point. The cut-off point is the point at which the transistor is turned off. This happens when the base-emitter voltage is below the threshold voltage. When the transistor is in cut-off, it acts like an open circuit.
• Saturation point. The saturation point is the point at which the transistor is turned on. This happens when the base-emitter voltage is above the saturation voltage. When the transistor is in saturation, it acts like a short circuit.
• Quiescent point. The quiescent point (Q-point) is the steady-state operating point of a transistor amplifier. It is the point at which the transistor is biased so that it operates in the linear region. The Q-point is determined by the values of the bias resistors and the input signal.

I hope this helps!
