Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.

12*6*3*2*8*4

Given: 12*6*3*2*8*4​​

Replace the * sign in the given equation with the mathematical signs and then solve the equation using the BODMAS rule.

​$$\begin{array}{|c|c|} \hline \textbf{Operation preference wise} & \textbf{Symbol} \\\hline Brackets &[],{}, () \\ \hline Orders, of & (power), √ (root) , of \\ \hline Division& ÷ \\ \hline Multiplication & × \\ \hline Addition & + \\ \hline Subtraction & - \\\hline \end{array}$$

12 + 6 $$\times$$ 3 $$-$$ 2 $$\div$$ 8 = 4

12 + 6 $$\times$$ 3 $$-$$ 0.25 = 4

12 + 18 $$-$$ 0.25 = 4

30 $$-$$ 0.25 = 4

29.75 $$\neq$$ 4 (This option does not satisfy the equation)​

12 + 6 $$\times$$ 3 $$-$$ 2 = 8 $$\div$$ 4

12 + 6 $$\times$$ 3 $$-$$ 2 = 2

12 + 18 $$-$$ 2 = 2

30 $$-$$ 2 = 2

28 $$\neq$$ 2 (This option does not satisfy the equation)​​

12 + 6 $$-$$ 3 $$\times$$ 2 $$\div$$ 8 = 4

12 + 6 $$-$$ 3 $$\times$$ 0.25 = 4

12 + 6 $$-$$ 0.75 = 4

18 $$-$$ 0.75 = 4

17.25 $$\neq$$ 4 (This option does not satisfy the equation)​​

12 $$\div$$ 6 $$-$$ 3 $$\times$$ 2 + 8 = 4

2 $$-$$ 3 $$\times$$ 2 + 8 = 4

2 $$-$$ 6 + 8 = 4

10 $$-$$ 6 = 4

4 = 4 (This option satisfies the equation)

Thus, only option (d) satisfies the equation.

So, the correct answer is option (d).
