As you go posteriorly from incisors to molars in both the maxillary and mandibular arches, the proximal contact area moves:

As you move from the incisors to the molars in both the maxillary and mandibular arches, the position of the proximal contact areas indeed shifts in a particular manner. In general, the contact area for posterior teeth is located more towards the gingival margin compared to the incisors.

This means that as you transition from anterior teeth (incisors and canines) to posterior teeth (premolars and molars), the proximal contact areas tend to move gingivally. Additionally, the contact areas also shift slightly towards the lingual aspect due to the rounded shapes and anatomy of the posterior teeth. This anatomical arrangement helps in maintaining proper occlusion and ensures adequate interproximal contact which is essential for dental health.

The other options do not accurately describe the movement of proximal contact areas as they transition from anterior to posterior teeth. Specifically, movements toward the occlusal surface or toward the facial/buccal area do not align with the observed anatomical patterns of tooth contact in the maxillary and mandibular arches.
