Correct answer: C
A Finite State Machine (FSM) simulator is a software tool used to design, visualize, and test the behavior of abstract computational models like Deterministic Finite Automata (DFA) and Non-Deterministic Finite Automata (NFA). It allows developers and computer scientists to construct a graph of states, transitions, and input symbols, and then trace exactly how the system moves from one state to another when given an input string. This simulation is critical for verifying the correctness of regular expressions, lexical analyzers, or sequential logic circuits before they are permanently implemented in hardware or software.
