In case of a concave mirror, if an object is kept between principal focus F and pole P of the mirror, then which one of the following statements about the image is NOT correct?

When an object is placed between the principal focus (F) and the pole (P) of a concave mirror, the reflected rays diverge and do not meet in front of the mirror. Instead, they appear to intersect behind the mirror, forming a virtual and erect image. This specific position results in an image that is enlarged or magnified compared to the object. According to the properties of concave mirrors, an image is formed at infinity only when the object is placed exactly at the principal focus (F), where the reflected rays emerge parallel to each other. Therefore, the statement claiming the image will be formed at infinity is incorrect for an object located between F and P. This configuration is commonly utilized in shaving mirrors or makeup mirrors to provide a magnified, upright view of the face.
