A search algorithm is exploring a graph with the following direct connections: Node A is connected to Node B and Node C; Node B is connected to Node A and Node D; Node C is connected to Node A; Node D is connected to Node B. The algorithm's current set of states is C = {Node A}. If the expansion function is defined as C' = Expand(C, f), where the rule f is 'identify all unique nodes that are directly connected to any node in the current set C', what is the resulting new set of states C'?
