If the image of an object, formed by a concave mirror is virtual, erect and magnified, then the object is placed

at the principal focus
at the centre of curvature
beyond the centre of curvature
between the pole of the mirror and the principal focus

A concave mirror forms a virtual, erect, and magnified image when the object is placed between its pole (P) and principal focus (F). In this position, rays from the object diverge after reflection and appear to originate from a point behind the mirror, forming a virtual image.
Image formation by a concave mirror depends on the object’s position. A virtual, erect, and magnified image is formed when the object is within the focal length (between P and F).
When the object is placed at the principal focus, the image is formed at infinity (real, inverted, highly magnified). When the object is at the centre of curvature, the image is also at the centre of curvature (real, inverted, same size). When the object is beyond the centre of curvature, the image is formed between the principal focus and the centre of curvature (real, inverted, diminished).
