Which of the following is not a reason for distortion in amplifier out

1.	Which of the following is not a reason for distortion in amplifier output?(a) Incorrect biasing level(b) Sinusoidal input(c) Non- linear amplification(d) Large input signalI got this question in an online interview.My question is from Distortion in Amplifier-1 topic in chapter Power Amplifier of Analog Circuits
Answer» Right answer is (d) Large input SIGNAL Explanation: Incorrect BIASING level that is, if biasing level is not properly managed improper GAIN may LEAD to distortion. Non-linear amplification is a COMMON reason for distortion in the case of transistor. If the input signal is large then output exceed the maximum peak of output that can be provided by an amplifier.
