Final answer:
The correct answer when referring to a potato is 'c) La papa', which is the Spanish term for 'the potato'; the other options represent different items in French and Spanish.
Step-by-step explanation:
When you see a potato, you write: c) La papa. Each option provided is in a different language and correlates to a different item. La tomate translates to 'the tomato' in French, which is not the correct answer. Le poisson means 'the fish' in French, again not matching a potato. La papa is Spanish for 'the potato', which is the correct match. Lastly, el pan translates to 'the bread' in Spanish, which is not the correct answer either.
