What does cascading of two transistor amplifiers imply?(a) Output of f

1.	What does cascading of two transistor amplifiers imply?(a) Output of first stage sent to input of second stage(b) Output of first stage sent to coupling device(c) Input of first stage sent to input of second stage(d) Not relatedThe question was asked during an interview.This intriguing question comes from The Cascode Transistor Configuration topic in section Low Frequency Transistor Amplifier Circuit of Electronic Devices & Circuits
Answer» Correct answer is (b) Output of first STAGE SENT to coupling device For EXPLANATION: In multi-stage amplifiers, the output of first stage is coupled to the input of SECOND stage using a coupling device. The coupling devices is typically a capacitor or a transformer. Cascading is known as the process of combining two AMPLIFIER stages using a coupling device.
