Correct Answer (Detailed Explanation is Below)
B.
7
Detailed Explanation
Evaluate the postfix expression from left to right using a
stack. Push 8, then 2. The / operator removes 2 and 8 and computes 8 / 2 = 4. Push 4 onto the stack, then push 3. The + operator computes 4 + 3 =
7. Therefore, the final result is 7. In postfix evaluation, for a binary operator, the first popped value is the
right operand and the second popped value is the left operand.
