Let $$f:\left[ {0,1} \right] \to R$$ (the set of all real numbers) be a function. Suppose the function $$f$$ is twice differentiable,
$$f(0) = f(1)=0$$ and satisfies $$f''\left( x \right) - 2f'\left( x \right) + f\left( x \right) \ge .{e^x},x \in \left[ {0,1} \right]$$.

If the function $${e^{ - x}}f\left( x \right)$$ assumes its minimum in the interval $$\left[ {0,1} \right]$$ at $$x = {1 \over 4}$$, which of the following is true?

A
$$f'\left( x \right) < f\left( x \right),{1 \over 4} < x < {3 \over 4}$$
B
$$f'\left( x \right) > f\left( x \right),0 < x < {1 \over 4}$$
C
$$f'\left( x \right) < f\left( x \right),0 < x < {1 \over 4}$$
D
$$f'\left( x \right) < f\left( x \right),{3 \over 4} < x < 1$$
