What is the result of positive feedback among the following ones ?

a. Increase in amplification & stability
b. Increase in amplification with reduced stability
c. Reduction in amplification and stability
d. Decrease in amplification with increased stability

Correct Answer : b. Increase in amplification with reduced stability

Explanation :

Positive feedback regenerates the amplification level by reducing stability to some extent.
