    Correct option is B

    Information Given:
    Original: 24 × 6 − 5 ÷ 4 + 10
    Interchange:
    + ↔ −
    × ↔ ÷
    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}​​
    After interchange:
    24 ÷ 6 + 5 × 4 − 10
    Now solve:
    24 ÷ 6 = 4
    5 × 4 = 20
    Expression becomes:
    4 + 20 − 10
    4 + 20 = 24
    24 − 10 = 14
    Final Answer:
    14
    Final Correct Option:
