The Correct Option is A

Explanation:

a x^{2} + b y^{2} + 2 h x y + 2 g x + 2 f y + c = 0

represents ellipse if

h^{2} - a b < 0

3 x^{2} + 12 y^{2} - 4 x + 4 y - 1 = 0

h = 0, a = 3, b = 12

h^{2} - a b < 0

A square with each side equal to \( a \) lies above the \( x \)-axis and has one vertex at the origin. One of the sides passing through the origin makes an angle \( \alpha \) (\( 0 < \alpha < \frac{\pi}{4} \)) with the positive direction of the \( x \)-axis. The equation of the diagonals of the square is:
