Answer #1

D-Latch: Latch continuosly check input and change the output correspondingly. It is level trigerred, when enable (C in this case) is HIGH output changes with input. When enable is LOW is continues its previous state.

D- Flip Flop: Flip-Flop continuosly check its inputs and change the output correspondingly only at times determined by clocking signal.(Negative triggered in this case).

So QA changes along with input when C is HIGH.

QB changes only when Clock changes from Positive to negative.

Here is the Completed waveforms for the circuit.
