Which statement is TRUE about goal test? (checking whether a search algorithm has found the goal state)
A. For uniform-cost search, goal test should be performed right after creating a node and before pushing it into the frontier.
B. For A* search, goal test should be performed right after creating a node and before pushing it into the frontier.
C. For uniform-cost search and A* search, goal test should be performed right after pushing a node into the frontier.
