The Difference Between a D- Latch and an Edge- Triggered

Multiple Choice

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) triggers on either the rising or falling edge of an ENABLE signal rather than the CLK input logic level.
C) always "latches" the Q output to the D input regardless of other inputs.
D) always "latches" the Q output to the complement of the D input regardless of other inputs.
