4. Choose the true claim about the behavior of the A* search algorithm. (a) Uniform-cost search will never expand more nodes than A* search. (b) Depth-first search will always expand more nodes than breadth-first search. (c) Adding the same positive constant c to every transition cost never changes the shortest path found by the A* algorithm. (d) The heuristic h(n) = c(n), where c(n) is the true cheapest cost to get from the node n to the nearest goal
