Why are we worried about β during the Collector feedback configuratio

1.	Why are we worried about β during the Collector feedback configuration?(a) To maintain a stable q-point irrespective of β(b) To increase the gain(c) To decrease the output impedance(d) To maintain a stable input impedanceI have been asked this question during a job interview.The above asked question is from Collector Feedback Configuration topic in section Transistor Biasing and Low Frequencies of Analog Circuits
Answer» The correct OPTION is (a) To maintain a stable q-point irrespective of β Explanation: If we change the DEVICE, β changes. But we want to keep the q-point stable so that CIRCUIT if represented as a black box, would provide the same characteristics and not be highly DEPENDENT on the transistor. Hence, we want to MAKE the circuit insensitive to β.
