Let the equation of a straight line L in complex form be az +z+b = 0, where a is a complex number and b is a real number, then (A) (B) (C) (D) Z-ci(Z-c) + the straight line a a point c (where c is a complex number) Z-c_i(z-c) the straight line a a c (where c is a complex number) 0 makes an angle of 45 with L and passes through a makes an angle of 45 with L and passes through a point the complex slope of the line L is the complex slope of the line L is a a a a
