    The degree of the differential equation\[{{\left( \frac{{{d}^{2}}y}{d{{x}^{2}}} \right)}^{2}}+{{\left( \frac{dy}{dx} \right)}^{2}}=x\sin \left( \frac{{{d}^{2}}y}{d{{x}^{2}}} \right)\]

    A)  1                                            

    B)  2

    C)  3                            

    D)         None of these

    Correct Answer: D

    Solution :

    Clearly, the given differential equation is not a polynomial in differential coefficients. So, its degree is not defined.
