Correct option is B

​    Given:
​'+' and '×' are interchanged
Operation preference wiseSymbolBrackets[],,()Orders, of(power),(root),ofDivision÷Multiplication×Addition+Subtraction\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}
Let's check options:
Option A: 20×2+5÷1-6=29
20 + 2 × 5 ÷ 1 − 6 = 29
20 + 2 × 5 − 6 = 29
20 + 10 − 6 = 29
30 − 6 = 29
24 \not= 29
Option B: 38-14+2×6÷3=12​
​38 - 14 × 2 + 6 ÷ 3 = 12
38 - 14 × 2 + 2 = 12
38 - 28 + 2 = 12
40 - 28  = 12
12 =12 (Follow)
Thus, the correct option is: (b)
