    A.

    2-40÷10÷6×8=5

    B.

    20÷7-30+6÷2=43

    C.

    10-2÷4×10+5=32

    D.

    Correct option is D

    Given:-

    Operation preference wiseSymbolBrackets[],,()Orders,of(power),(root),ofDivision÷Multiplication×Addition+Subtraction\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}Solution:-2 - 40 + 10 ÷ 6 × 8 = 5

    2 × 40 ÷ 10 + 6 - 8 = 5

    8 +6 - 8 = 5

    6 = not 5

    20 ÷ 7 - 30 + 6 ÷ 2 = 43

    20 + 7 × 30 ÷ 6 + 2

    20 + 35 + 2

     = 57 not 43

    10 - 2 ÷ 4 × 10 + 5 = 32

    10 × 2 + 4 - 10 ÷ 5

    20 + 4 - 2 = 22 not 32

    10 ÷ 5 - 4 × 18 + 3 = 24

    10 + 5 × 4 - 18 ÷ 3

    10 + 20 - 18 ÷ 3

    30 - 6

    = 24

    Thus, the correct answer is option (D) 10 ÷ 5 - 4 × 18 + 3 = 24
