The correct answer is A. Q will flip from 0 to 1.
An RS flip-flop is a type of bistable multivibrator, a device with two stable states, which can be used to store one bit of information. The two states are represented by
the binary digits 0 and 1. The output of the flip-flop is Q, and the input is S.When both inputs are set to 0, the flip-flop is in the reset state, and the output is 0. If a momentary ‘1’ is applied at the input S, the flip-flop will go to the set state, and the output will flip from 0 to 1. If the input S is then returned to
0, the flip-flop will remain in the set state, and the output will remain at 1.The other options are incorrect because they do not describe the correct behavior of the RS flip-flop.
