C Correct answer
Explanation

This is the correct match. In March 2007, Langanin (a protein found in Langerhans cells) was published as natural barrier to HIV-1; Merkel cells were considered to be APUD (Amine Precursor Uptake Decarboxylase ) cells; tyrosinase is required for melanocytes to produce melanin from the amino acid tyrosine; and a sunburn cell is a keratinocyte with a pyknotic nucleus.
