On Checking and Interchanged each option one by one:
1) 12 + 4 - 4 ÷ 2 = 3
By interchanging - and ÷ in the given equations.
Interchanged equation is: 12 + 4 ÷ 4 - 2 = 3
⇒ 12 + 1 - 2 = 3
⇒ 13 - 2 = 3
⇒ 11 ≠ 3
⇒ LHS ≠ RHS
2) 6 ÷ 3 + 12 - 6 = 5
By interchanging - and ÷ in the given equations.
Interchanged equation is: 6 - 3 + 12 ÷ 6 = 5
⇒ 6 - 3 + 2 = 5
⇒ 8 - 3 = 5
⇒ 5 = 5
⇒ LHS = RHS
3) 12 ÷ 3 + 9 - 9 = 4
By interchanging - and ÷ in the given equations.
Interchanged equations is: 12 - 3 + 9 ÷ 9 = 4
⇒ 12 - 3 + 1 = 4
⇒ 13 - 3 = 4
⇒ 10 ≠ 4
⇒ LHS ≠ RHS
4) 9 ÷ 9 - 9 + 9 = 9
By interchanging - and ÷ in the given equations.
Interchanged equations is: 9 - 9 ÷ 9 + 9 = 9
⇒ 9 - 1 + 9 = 9
⇒ 18 - 1 = 9
⇒ 17 ≠ 9
⇒ LHS ≠ RHS
Hence, the correct answer is "Option 2".
