An object is placed at a distance of \(40\) cm from a concave mirror of a focal length of \(15\) cm. If the object is displaced through a distance of \(20\) cm towards the mirror, the displacement of the image will be:

1. \(30\) cm away from the mirror
2. \(36\) cm away from the mirror
3. \(30\) cm towards the mirror
4. \(36\) cm towards the mirror
