French Opinions and Preferences

In French, the partitive article (du, de la, de l' or des) means 'some' and is often used even when 'some' might be omitted in English. Given the sentence structure 'Je mange ___ poulet avec ___ frites' (I'm eating chicken with chips), which of the following pairs of partitive articles correctly completes the sentence, keeping in mind 'poulet' is masculine singular and 'frites' is feminine plural?
