• A. If a lens is used to obtain the image, then it must be a converging lens and its optical center will be the intersection point of line $AB$ and $OI$
• B. If a lens is used to obtain the image, then it must be a diverging lens and its optical center will be the intersection point of line $AB$ and $OI$
• C. If a mirror is used to obtain the image, then the mirror must be concave and the object and image subtend equal angles at the pole of the mirror
• D. $I$ is a real image
