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)

Answer 3 is right. One more difference is that fllipflops
take twice the number of gates as latches
2) so automatically delay is more for flipflops
3)power consumption is also more.

Answer / chandrasheka kakanur
Latches are Level sensitive and the input values are
assigned only at the levels and latches does not require
less power consumtion than flip flops. Flip flops are edge
sensitive, as per assignment of clock the values are
assigned at a particular edge.

Answer / naeem khan
the difference between latche and flip flop is that , that
latchs used the level clock trigger while the flip flop
used the edge trigger clock.so this the is main difference
between the latchs and flip flop.

Answer / k.n.n.sarma
LATCH-LEVEL SENSITIVE
IT CONSISTS OF BOTH ENABLE AND CLOCK
FLIP FLOP-EDGE TRIGGERED
IT CONSISTS OF ONLY CLOCK AND NO ENABLE IS PRESENT FOR FLIP
FLOP.

Answer / harsh agrawal
In electronics, a latch is a kind of bistable multivibrator,
an electronic circuit which has two stable states and
thereby can store one bit of information. Today the word is
mainly used for simple transparent storage elements, while
slightly more advanced non-transparent (or clocked) devices
are described as flip-flops. Informally, as this distinction
is quite new, the two words are sometimes used interchangeably.

Answer / alekhya
latches are used as temperory buffers where as fliflops
used as registers
