The output of the AND gate will remain 0 after the lower input to the flip-flop returns to 0.

The output of the AND gate will remain 0 after the lower input to the flip-flop returns to 0. Here’s a step-by-step breakdown of this process: 1. Initial State: The lower input to the flip-flop is initially at 1. However, this input is negated by the NOT gate, turning it into 0. This causes the output of the AND gate to become 0. 2. During Transition: When the lower input to the flip-flop returns to 0, the NOT gate negates this input, maintaining the output of the AND gate at 0. 3. After Transition: At this point, both inputs to the OR gate are 0 (since the upper input to the flip-flop is held at 0). As a result, the output of the OR gate also becomes 0. In conclusion, the output of the AND gate remains at 0 after the lower input to the flip-flop returns to 0, regardless of the changes in the state of the flip-flop. This is because the NOT gate negates the lower input, and the OR gate outputs 0 when both its inputs are 0.
