Which measurement represents the smallest object-to-image distance (OID) among the options?

Explanation:
Object-to-image distance affects how much the anatomy is magnified and how sharp the image will appear. A smaller distance reduces magnification and geometric unsharpness, so edges look crisper and details are more visible. Among the options, the shortest distance will produce the least magnification and the sharpest image, making it the correct choice. The other distances are longer, which increases magnification and blur, degrading detail.
