A. If both Assertion \& Reason are True \& the Reason is a correct explanation of the Assertion.
B. If both Assertion \& Reason are True but Reason is not a
\( \mathrm{P} \) correct explanation of the Assertion.

W
C. If Assertion is True but the Reason is False.
D. If both Assertion \& Reason are False.
Assertion :- An external input is necessary to sustain ac signal in the output for an amplifier, whereas in an oscillator we get ac output without any external input signal.

Reason :- In an oscillator a portion of the output is returned back (feedback) to the input in phase with the input.
