ACc blocks any AC component associated with the input from reaching the base. Cbp helps minimize degeneration of the AC output signal.
BCc blocks any DC component associated with the input from reaching the base. Cbp helps maximize degeneration of the AC output signal.
CCc blocks any DC component associated with the input from reaching the base. Cbp helps minimize degeneration of the AC output signal.
DCc blocks any AC component associated with the input from reaching the base. Cbp helps maximize degeneration of the AC output signal.
AI Explanation

The correct answer is C. The coupling capacitor Cc blocks any DC component associated with the input from reaching the base of the transistor, while the bypass capacitor Cbp helps minimize degeneration of the AC output signal. This configuration is commonly used in amplifier circuits to isolate the DC bias conditions from the AC signal path, ensuring stable and efficient amplification of the input signal. The other options are incorrect because: A) Cc blocks DC, not AC, from reaching the base. B) Cbp helps minimize, not maximize, degeneration of the AC output signal. D) Cc blocks DC, not AC, from reaching the base, and Cbp helps minimize, not maximize, degeneration of the AC output signal.
