Under which of the following conditions a concave mirror can form an image larger than the actual object?

Options

• When the object is kept at a distance equal to its radius of curvature

• When object is kept at a distance less than its focal length

• When object is placed between the focus and centre of curvature

• When object is kept at a distance greater than its radius of curvature
