Give the order of the differential equation below, where y represents a function of the variable x.y-2y'-x²y" = 5Choose the correct answer below.A. The given equation is a second-order differential equation because it involves a second derivative but no higher derivative.B. The given equation is a first-order differential equation because it only involves a first derivative.C. The given equation is a third-order differential equation because it involves a third derivative but no higher derivative.D. The given equation is a first-order differential equation because it involves a first derivative but no higher derivative.
