Correct answer: B

To determine the next state, we analyze the given transition rules for the sequential circuit. The problem specifies that when the current state is A, the next state depends entirely on the input value. If the input is 0, the circuit remains in state A. However, if the input is 1, the circuit transitions to state B. Since the question asks for the next state when the current state is A and the input is 1, we directly apply the second rule. This confirms that the circuit moves from state A to state B. Therefore, option B is correct because it matches the specified transition condition for input 1. Option A (state A) would only be correct if the input were 0, and option C (state C) is incorrect because no rule defines a transition to state C from state A under any input condition.
