If f is twice differentiable such that f(x) = –f(x) and f'(x) = g(x). If h(x) is a twice differentiable function such that h'(x) = (f(x))2 + (g(x))2 . If h(0) = 2, h(1) = 4, then the equation y = h(x) represents
(A) a curve of degree 2
(B) a curve passing through the origin
(C) a straight line with slope 2
(D) a straight line with y intercept equal to 2.
