Which statement best describes the operation of a NGT- triggered D flip- flop?
A) The Q output is always identical to the D input.
B) The Q output is always identical to the CLK input if the D input is HIGH.
C) The Q output is always identical to the D input when CLK makes a PGT.
D) The logic level at the D input is transferred to Q on NGT of CLK.

Question

The correct statement is D because in a negative-edge triggered (NGT) D flip-flop, the logic level present at the D input is captured and transferred to the Q output specifically on the negative transition (or falling edge) of the clock signal (CLK). This means that changes at the D input at other times do not affect the Q output until the next negative edge of the clock.
