D-latch & edge-triggered D-type flip-flop

The difference between a D-latch and an edge-triggered D-type flip-flop is that the latch:

A)
is controlled by the logic level at its ENABLE input rather than a CLK transition.
B)
always "latches" the Q output to the D input regardless of other inputs.
C)
triggers on either the rising or falling edge of an ENABLE signal rather than the CLK input logic level.

Thanks...this is the only one i got wrong on the test n i can't figure it out

I think Option A is the right answer as Latch saves the input state to the output pin while there is Enable Input.

I think its C
Since only the difference between the d flip flop and Edge-triggered flip flop is the way its triggered the enable signal
So i feel its C
