Answer:
A. Flip-flops will never change state more than once per clock cycle, but latches can change state multiple times during a clock pulse.
Explanation:
Even though both flip-flops and latches are sequential circuits (which means that the present outputs don´t depend on the current value of the inputs and outputs but on the previous ones, so it is said that these circuits have memory), the flip-flops state changes are only valid when a clock pulse is present, which means that it can´t change state more than once per clock cycle .
Latches, instead, change state no sooner a input level changes, so it doesn´t need for a clock pulse to be present.
