Circuit stability refers to the ability of a circuit to maintain a consistent gain or output, regardless of variations in input or operating conditions. In this case, we are comparing the stability of three circuits: P, Q, and R.
1. Circuit P: Desensitivity of 20
Desensitivity refers to the ability of a circuit to withstand variations in its elements without significant changes in its performance. A higher desensitivity value indicates better stability. Therefore, circuit P with a desensitivity of 20 is relatively stable in gain.
2. Circuit Q: Sensitivity of 0.1
Sensitivity is the reciprocal of desensitivity and represents the change in output per unit change in input. A lower sensitivity value indicates better stability. Circuit Q has a sensitivity of 0.1, which means it is relatively stable in gain.
3. Circuit R: Desensitivity of 40
Circuit R has a desensitivity of 40, which is higher than both circuit P and Q. Therefore, circuit R is the most stable in gain among the three circuits.
4. Comparison and Conclusion
Comparing the desensitivity and sensitivity values of the three circuits, we can conclude that circuit R is the most stable in gain. Circuit P and circuit Q are also stable but to a lesser extent. Therefore, the correct answer is option C: Circuit R.

Greater desensitivity indicates better stability in gain. More desensitivity means gain becomes smaller, but stable.
For circuit Q, desensitivity = 1/S = 10
Circuit R has higher desensitivity, hence most stable.
For circuit Q, desensitivity = 1/S = 10
Circuit R has higher desensitivity, hence most stable.
