Choose the appropriate combination of signs to solve the given equation.
​(23 - 5) * (12 $$\div$$ 2) * 3 * 16​

Given: ​(23 - 5) * (12 $$\div$$ 2) * 3 * 16

Given equation is solve by BODMAS rule.

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

Now, we check each options.

Option (a): + + =

New equation: (23 - 5) + (12 $$\div$$​ 2) + 3 = 16

18 + 6 + 3 = 16

27 $$\neq$$ 16​

Option (b): - $$\div$$​ = 

New equation: (23 - 5) - (12 $$\div$$​​ 2) $$\div$$​ 3 = 16

18 - 6 $$\div$$ 3 = 16

​18 - 2 = 16

​Option (c): ​$$\times$$ $$\div$$​ =

New equation: (23 - 5) $$\times$$​ (12 $$\div$$​ 2) $$\div$$​ 3 = 16

18 $$\times$$ 6 $$\div$$ 3 = 16

​18 $$\times$$​ 2 = 16

36 $$\neq$$ 16​

Option (d): + - =

New equation: (23 - 5) + (12 $$\div$$​ 2) - 3 = 16

18 + 6 - 3 = 16

24 - 3 = 16

21 $$\neq$$ 16

Thus, correct option is (b).
