Differences between D-Latch and D flip-flop?

Answer Posted / abc

Answer 2 is wrong. latch can have a clock. Answer 1 is correct.
elaborating on it: difference is that for a latch the output
can follow input(like a buffer) if latch is in "pass" state,
else if the clock input is such that the its in "latch"
state then output is preserved. Whereas, flip-flop output
only changes at the clock edge(rising or falling depending
upon type of flop)
