*🔴Correct Answer:* B) 2nd
*Explanation:* 🤓
The 2nd Purkinje image (II) is the anterior-most because it forms by reflection from the steeper posterior corneal surface (radius ~6.4 mm), which causes greater light convergence. In contrast, the 1st Purkinje image (I) forms at the flatter anterior cornea (radius ~7.8 mm), leading to more divergent reflection, positioning it slightly posteriorly. This stronger convergence of 2nd Purkinje reflected rays makes it appear closer to the observer, despite forming at a deeper surface.
