Given: 56 – 12 × 4 ÷ 9 + 5 = ?

According to the question, after ‘+’ and ‘–’ are interchanged, and ‘×’ and ‘÷’ are interchanged:

56 – 12 × 4 ÷ 9 + 5 = ? ⇒ 56 + 12 ÷ 4 × 9 5 = ?

⇒ 56 + 12 ÷ 4 × 9  5 = ?

⇒ 56 + 3 × 9  5 = ?

⇒ 56 + 27  5 = ?

83  5 = ?

⇒ 78 = ?

Hence, "Option 2" is the correct answer.
