(b) $-W$

Work Step by Step

A small positive charge is fixed at Origin. And an electron is brought near it from a large distance away. The magnitude of work taken to move the electron is W. Since, change in system's electrostatic potential energy is negative of work done which is work taken, the sign here will be negative. $(b)-W$ is the answer.
