Assume we run pruning, expanding successors from left to right, on a game with tree as shown in Figure (a) below. Mark the correct option below.

(a) There exists an assignment of utilities to the terminal nodes such that no pruning will be achieved (shown in Figure (a)).

(b) There exists an assignment of utilities to the terminal nodes such that the pruning shown in Figure (b) will be achieved.

(c) There exists an assignment of utilities to the terminal nodes such that the pruning shown in Figure (c) will be achieved.

(d) None of the above
