Which of the following things would you need if you wanted to write a letter?

To write a letter, you need paper to write on. “Les feuilles de papier” means “sheets of paper,” so choice C is correct. “La carte” means a card or map, “la pendule” is a clock, and “le bureau” is a desk or office; none of these is the paper itself.
