The Correct Option is C
Solution and Explanation
Given differential equation is
$y =x \frac{d y}{d x}+\frac{2}{d y / d x}$
$\Rightarrow y \frac{d y}{d x}=x\left(\frac{d y}{d x}\right)^{2}+2$
Here, order $=1$ and degree $=2$
$y =x \frac{d y}{d x}+\frac{2}{d y / d x}$
$\Rightarrow y \frac{d y}{d x}=x\left(\frac{d y}{d x}\right)^{2}+2$
Here, order $=1$ and degree $=2$

Concepts Used:
Order and Degree of Differential Equation
The equation that helps us to identify the type and complexity of the differential equation is the order and degree of a differential equation.
The Order of a Differential Equation:
The highest order of the derivative that appears in the differential equation is the order of a differential equation.
The Degree of a Differential Equation:
The highest power of the highest order derivative that appears in a differential equation is the degree of a differential equation. Its degree is always a positive integer.
For examples:
- 7(d4y/dx4)3 + 5(d2y/dx2)4+ 9(dy/dx)8 + 11 = 0 (Degree - 3)
- (dy/dx)2 + (dy/dx) - Cos3x = 0 (Degree - 2)
- (d2y/dx2) + x(dy/dx)3 = 0 (Degree - 1)
