If f is twice differentiable such that ...

If `f` is twice differentiable such that `f^('')(x)=-f(x)` and `f^(prime)(x)=g(x)dot` If `h(x)` is twice differentiable function such that `h^(prime)(x)=(f(x))^2+(g(x))^2dot` 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.
