Which statement describes the BEST operation of a negative-edge-trigge

1.	Which statement describes the BEST operation of a negative-edge-triggered D flip-flop?(a) The logic level at the D input is transferred to Q on NGT of CLK(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 = PGT(d) The Q output is ALWAYS identical to the D inputThis question was addressed to me in homework.This question is from D Flip Flop in chapter Flip-Flops of Digital Circuits
Answer» Correct option is (a) The logic level at the D input is transferred to Q on NGT of CLK Explanation: By the truth table of D flip FLOP, we can observe that Q always DEPENDS on D. HENCE, for every negative trigger PULSE, the logic at input D is SHIFTED to Output Q.
