Spheres of unit diameter are centered at (l,m,n)(l, m, n) where ll, mm, and nn take every possible integer values.

The distance between two spheres is computed from the center of one sphere to the center of the other sphere. For a given sphere, xx is the distance to its nearest sphere and yy is the distance to its next nearest sphere. The value of yx\frac{y}{x} is:

A
222\sqrt{2}
B
12\frac{1}{\sqrt{2}}
C
2\sqrt{2}
D
