A point 
in the plane is called a lattice point if both 
and 
are integers. The area of the largest square that contains exactly three lattice points in its interior is closest to
Solution 1
Sadly, I don't actually have a solution. However, after doing some work on Geogebra, I have convinced myself that the answer is almost certainly A
Solution 2
Apply Pick's Theorem. 4 lattice points on the border edges, 3 points in the interior. 
, implying that
