Correct Answer : Option (A) : Flip-flop
Explanation : A flip-flop refers to an electronic circuit with two stable states that can be used to store the binary data (1,0). Flip-flop can store only one bit of data, either a logic 1 or 0. This logic state can be represented as the voltage on the flip-flop's output because it can be controlled to hold the logic state, effectively a 1 -bit memory.
