Vedclass · Answer

(B) The order of a differential equation is defined as the order of the highest derivative present in the equation.In option $A$,the highest derivative is $y'$,which is of order $1$.In option $B$,the highest derivative is $y''$,which is of order $2$.In option $C$,the highest derivative is $y'''$,which is of order $3$.In option $D$,the highest derivative is $y'$,which is of order $1$.Therefore,the second-order differential equation is $y'y'' + y = \sin x$.
