Correct Answer: B

The subcutaneous layer (A) is deeper and primarily consists of fat cells. The reticular layer (C) is deeper than the papillary layer and mainly provides structural support. Hypodermal (D) is not a recognized skin layer term. Thus, the papillary layer is the correct choice due to its proximity to the skin surface and functions related to blood vessels and nerves.
