The correct answer is C. A combination of different vegetables
Step-by-step explanation:
The term "mirepoix" is used in gastronomy to refer to two or more vegetables that have been chopped or diced and are used as a base for soups, casseroles, sauces, among others. For example, one of the most common mirepoix includes celery, onions, and carrots; although the vegetables used vary depending on the country or culture. Besides this, the mirepoix is often cooked on a low heat because this boosts the flavor of the vegetables. According to this, mirepoix refers to "a combination of different vegetables".
