Show answer & explanation
Correct answer: A
The correct answer is 1) When the clock is Negative. Negative Level Triggered: The flip-flop (or more accurately, a latch) is "transparent" and can change its state as long as the clock signal remains at a low level (Logic 0). During this time, the output will follow the changes in the input.
