Solution

The correct option is B $- 9 x - 5$
$4 - x^{2} \div x + (4 \times - (\frac{2 x^{3}}{x^{2}})) - 3^{2}$
We need to follow BODMAS rule.
=> Brackets (parts of a calculation inside brackets always come first).
=> Orders (numbers involving powers or square roots).
=> Division.
=> Multiplication.
=> Addition.
=> Subtraction.
$=$ $4 - x^{2} \div x + (4 \times - (\frac{2 x^{3}}{x^{2}})) - 3^{2}$
$=$ $4 - x + (4 \times - 2 x) - 9$
$=$ $4 - x - 8 x - 9$
$=$ $- 9 x - 5$
