The subpapillary plexus is
1. a deep network of dermal arteries along the boundary of the reticular layer.
2. a superficial network of dermal arteries.
3. a network of arteries in the epidermis.
4. a network of nerves in the cutaneous membrane.
5. a neural plexus responsible for deep pressure.

Explanation:

The skin of a human is divided into three portions: the epidermis, dermis and the hypodermis.  The dermis and the hypodermis possess the arteries which continuously supplies the blood to the skin.

The subpapillary plexus is one such network of arteries that supplies the blood to the dermis. The blood in the subpapillary plexus is the reason that the skin appears red or pink. When the skin appears red then the blood in the plexus is high.

Thus, Option-2 is correct.
