Show answer & explanation
Correct answer: A
In digital electronics, sequential logic circuits depend on memory elements to track past inputs and determine future actions. A Finite State Machine (FSM) relies entirely on this concept, as it must store its "current state" in order to compute the "next state" when a new clock pulse arrives. Flip-flops serve as the fundamental, hardware-level 1-bit memory cells that physically capture and hold these binary states on every clock edge, making them essential for state retention in any digital control loop.
