The diagram shows that two leaf nodes are multiplied first to yield 6, then added to yield 11, then more leaf nodes are added (5 and 4) to give 20, and finally that value is multiplied by the result of subtracting 1 from 6. This matches option C, which has the same order of operations: 2 * 3 is 6, which is added to 5 and 4 to make 15, and then that result is multiplied by 5 - 1, which is 4, yielding the final answer of 60.
