C
$0$
D
Undefined

Answer

Correct option: A.

$2$

Given, the differential equation is:
$2\text{x}^2\frac{\text{d}^2\text{y}}{\text{d}\text{y}^2}-3\frac{\text{dx}}{\text{dx}}+\text{y}=0$
Or we can write:
$2x^2 y\ ’’ – 3y\ ’ + y = 0$
Order is the highest derivative in the differential equation. Therefore, the order is $2.$
