  • The order of a differeential equation is the highest order to which it belongs
  • The degree of a differential equation is the power of the highest order differential coefficient
Given equation is
It is clearly that the highest order of eqauation is $\Large\frac{d^3y}{dx^3}$
Hence the order is $3$
The power of the highest order differential coefficient is $2$
Hence its degree is $2$
Clearly the above equation is a non-linear differential equation of order $3$ and degree $2$
Hence the correct option is $D$
