A square is inscribed in the circle `x^2+y^2-2x+4y-93=0`
with its sides parallel to the coordinate axes. The coordinates of its
vertices are
`(-6,-9),(-6,5),(8,-9),(8,5)`
`(-6,-9),(-6,-5),(8,-9),(8,5)`
`(-6,-9),(-6,5),(8,9),(8,5)`
`(-6,-9),(-6,5),(8,-9),(8,-5)`
A. (-6, -9), (-6, 5), (8, -9), (8, 5)
B. (-6, 9), (-6, -5), (8, -9), (8, 5)
C. (-6, -9), (-6, 5), (8, 9), (8, 5)
D. (-6, -9), (-6, 5), (8, -9), (8, -5)
