  1. Postfix = a b + c d * -e f + /

  2. Postfix = a b + c d - * e f + /

  3. Postfix = a b + c d - * / +

  4. Postfix = e f + a b + c d * - /

B Correct answer
Explanation

To convert (a + b) * (c - d) / (e + f) to postfix: first convert each subexpression (a+b)→ab+, (c-d)→cd-, (e+f)→ef+, then apply operators: ab+ cd- * gives the product, then ab+cd-* ef+ / gives the final division. Option B correctly shows: ab+ cd- * ef+ /. The other options either apply operators in wrong order or have misplaced operands.
