The answer is the second one: dermal papillae.

Explanation for each option:

  • Reticular papillae: This term is not typically used in the context of skin anatomy. The reticular layer is a deeper part of the dermis, but it does not have structures called "reticular papillae."
  • Dermal papillae: Correct. These are the folds or projections in the papillary layer of the dermis. They interlock with the epidermis and are responsible for the unique patterns of fingerprints.
  • Hair follicles: These are structures in the skin from which hair grows, but they are not folds in the papillary layer.
  • Sebaceous glands: These are oil-producing glands associated with hair follicles, not folds in the papillary layer.

Summary: The folds in the tissue of the papillary layer of the dermis are called dermal papillae.
