Which macular region is the most peripheral in nature?

Explanation:
Macula is organized in concentric zones around the fovea centralis. The central zone is the fovea, with the foveola right at its center, then surrounds the fovea by the parafovea, and outside that lies the perifovea. Because the perifovea forms the outer boundary of the macula, it is the most peripheral region within the macular area. It marks the transition from the high-acuity center to the more peripheral retina. Therefore, the perifovea is the correct region.
