If

\left| {z + 8} \right| + \left| {z - 8} \right| = 16

, where

z

is a complex number, then the point

z

will lie on

View answer and explanation

Correct option: C

A straight line

Option C (A straight line) is correct because the equation represents the locus of a point where the sum of its distances from two fixed points is constant, which degenerates into a straight line when the constant equals the distance between the fixed points.
