(A) Let $z = x + iy$. Substituting this into the equation: $|(x+1) + i(y-1)| = |(x-1) + i(y+1)|$. Squaring both sides: $(x+1)^2 + (y-1)^2 = (x-1)^2 + (y+1)^2$. Expanding the terms: $x^2 + 2x + 1 + y^2 - 2y + 1 = x^2 - 2x + 1 + y^2 + 2y + 1$. Simplifying: $2x - 2y = -2x + 2y$. $4x = 4y$,which implies $y = x$. The equation $y = x$ represents a straight line passing through the origin and the first and third quadrants.
