A convex lens forms a virtual, erect, and magnified image when the object is placed between its focus (F) and optic centre (O). This is a unique case where the image is formed on the same side of the lens as the object. Because the object is placed very close to the lens (within the focal length), the light rays after refraction diverge, and the lens appears to produce a larger image that is virtual and upright.
Hence, the image is larger than the object.
The correct option is (C): larger
