Redox reactions questions

Ascorbic acid (C$\text{}_{6}$start text, end text, start subscript, 6, end subscriptH$\text{}_{8}$start text, end text, start subscript, 8, end subscriptO$\text{}_{6}$start text, end text, start subscript, 6, end subscript) is a common antioxidant that protects our bodies against radicals. In the redox equation below that occurs in our stomach, which of the following pairs identifies the reducing and oxidizing agents, respectively?
