20 GATE Question Of The Day – Digital Electronics

For the circuit shown in the figure, D has a transition from 0 to 1 after CLK changes from 1 to 0. Assume gate delays to be negligible

 Which of the following statements is true?

            (A)        Q goes to 1 at the CLK transition and stays at 1

            (B)        Q goes to 0 at the CLK transition and stays at 0

            (C)        Q goes to 1 at the CLK transition and goes to 0 when D goes to 1

            (D)        Q goes to 0 at the CLK transition and goes to 1 when D goes to 1

Pick up the correct options guys just a simple thing for my well wished friend(s)!
