Solution

The correct option is B 1,1
$(2 x^{2} + y) d x + (x - 3 y)) d y = 0$

$(2 x^{2} + y) + (x - 3 y) \frac{d y}{d x} = 0$

$\Rightarrow$ Order= $1$ (Order of a differential equation is the order of the highest derivative (also known as differential coefficient) present in the equation.)

Degree= $1$ (The degree of differential equation is represented by the power of the highest order derivative in the given differential equation.)
