Given: [( 48 - 2) ÷ 23] × 19 + 3 = ?

After ‘÷’ and ‘-’ are interchanged and ‘×’ and ‘+’ are interchanged then,

[( 48 - 2) ÷ 23] × 19 + 3 = ? ⇒ [( 48 ÷ 2) - 23] + 19 × 3 = ?

⇒ [( 48 ÷ 2) - 23] + 19 × 3 = ?

⇒ [24 - 23] + 19 × 3 = ?

⇒ 1 + 19 × 3 = ?

+ 57 = ?

58 = ?

Hence, "Option 4" is the correct answer.
