Which of the following are types of stock in cooking?

The correct answer includes white, brown, and vegetable stocks, which are fundamental types of stock commonly used in cooking.

White stock is typically made from chicken or veal bones, simmered to extract flavor without browning the bones, resulting in a light, clear liquid. Brown stock, on the other hand, is made from roasted bones (often beef or veal) which gives it a rich color and deeper flavor due to the caramelization that occurs during roasting. Vegetable stock is made from a variety of vegetables, often including mirepoix (a mix of onions, carrots, and celery), and is a great option for vegetarian dishes.

Each of these stocks serves as a base for sauces, soups, and a multitude of other recipes, showcasing their essential role in classical cooking techniques. The other options do contain some types of stock, but they either mix incorrect pairings or include non-standard definitions that do not accurately represent the traditional categorization of stocks in culinary practice.
