  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. Stack

Detailed Explanation

A Stack is commonly used to evaluate postfix expressions because postfix evaluation requires operands to be temporarily stored until an operator is encountered. Operands are pushed onto the stack. When an operator appears, the required operands are popped, the operation is performed, and the result is pushed back. This process continues until the expression ends. If the postfix expression is valid, exactly one final result should remain on the stack.
