## Question

### Solution

Correct option is

Given equation is a homogeneous equation of second degree. So, lines represented by it intersect at the origin. Consequently, centre of the circle is at the origin. It is given that the lines represented by the given equation divide the circle into four sectors such that the area of one of the sectors is thrice that of the other. Let θ be the acute angle between the lines. Then, 3θ is the obtuse angle and so
