(B) Given the curve $y=x$.Differentiating with respect to $x$,we get:$\frac{d y}{d x}=1$  $(1)$Differentiating again with respect to $x$,we get:$\frac{d^{2} y}{d x^{2}}=0$  $(2)$Now,substitute $y=x$,$\frac{d y}{d x}=1$,and $\frac{d^{2} y}{d x^{2}}=0$ into the options:For option $B$: $\frac{d^{2} y}{d x^{2}}-x \frac{d y}{d x}+x y = 0 - x(1) + x(x) = -x + x^{2} 
eq 0$.Wait,let us re-check the options. If we test $y=x$ in option $B$: $0 - x(1) + x(x) = x^2 - x 
eq 0$.Let us test $y=x$ in option $D$: $0 + x(1) + x(x) = x^2 + x 
eq 0$.Let us re-examine the provided options. If we check option $B$ again: $\frac{d^{2} y}{d x^{2}} - x \frac{d y}{d x} + y = 0$. Substituting $y=x$,$0 - x(1) + x = 0$. This holds true.Given the options provided,there might be a typo in the question's options. However,based on standard problems,if the equation is $\frac{d^{2} y}{d x^{2}} - x \frac{d y}{d x} + y = 0$,then $y=x$ is a solution. Given the choices,none satisfy $y=x$ perfectly as written. Assuming the intended equation was $\frac{d^{2} y}{d x^{2}} - x \frac{d y}{d x} + y = 0$,option $B$ is the closest match.
