The formula for the maximum focus range or hyperfocal distance, H, of a camera is given by H = \frac{L^{2} }{f . C}, where L is the focal length of the lens, f is the setting on the camera to reduce or enlarge the aperture, and c is the diameter of the circle of least confusion. Which of the following expresses this same relationship between the quantities in terms of the focal length of the lens? I've been stuck on these kind of problems for weeks...please help.

Options are:
L = \sqrt{H . f . C}
L = \frac{f . c}{H^{2} }
L = \frac{H^{2} }{f . C}
L = H\sqrt{f . c}
