Question

Let s, t, r be non-zero complex numbers and L be the set of solutions z = x + iy (x, y ∊ R, i = √-1 ) of the
equation sz+tz+r=0 , where z=x-iy . Then, which of the following statement(s) is (are) TRUE ?
(A) If L has exactly one element, then |s| ≠ |t|
(B) If |s| = |t|, then L has infinitely many elements
(C) The number of elements in L ∩ {z : |z - 1 + i| = 5} is at most 2
(D) If L has more than one element, then L has infinitely many elements
