If `4t^(2)-5m(2)+6l+1=0`, then the line lx+my+1=0 touches the circle

A line is tangent to a circle if the length of perpendicular from the centre of the circle to the line is equal to the radius of the circle. If 4l^2 - 5m^2 + 6l + 1 = 0 , then the line lx + my + 1=0 touches a fixed circle whose centre. (A) Lies on x-axis (B) lies on yl-axis (C) is origin (D) none of these
