Solution
The correct option is C8 Since the chord makes equal intercept of length l on the coordinate axes, so its equation can be written in the form x±y=±l.
Since the chord intersect the given circle at two distinct points, therefore the length of the ⊥ from the center (0,0) of the given corcle to the chord must be less than the radius
