Match List-I with List-II:

List-I	List-II
The derivative of $\log_e x$ with respect to $\frac{1}{x}$ at $x = 5$ is	(I) -5
If $x^3 + x^2y + xy^2 - 21x = 0$ , then $\frac{dy}{dx}$ at $(1, 1)$ is	(II) -6
If $f(x) = x^3 \log_e \frac{1}{x}$ , then $f'(1) + f''(1)$ is	(III) 5
If $y = f(x^2)$ and $f'(x) = e^{\sqrt{x}}$ , then $\frac{dy}{dx}$ at $x = 0$ is	(IV) 0
