.20 Consider the differential equation y"+ay +y = sin x for x E R. *) Then which one of the following is true? Options A. Ifa = 0, then all the solutions of (**) are unbounded over R. B Ifa = 2, then all the solutions of (**) are bounded over (-o, 0). C. Ifa = 1, then all the solutions of (**) tend to zero as x co D. Ifa = 1, then all the solutions of (*) are unbounded over (0, oo).
