Which of the following is a type of meat derived from organ glands?

Sweetbreads are a specific type of meat that comes from the organ glands of animals, particularly the thymus gland (often referred to as the throat sweetbread) or the pancreas (the heart sweetbread). These glands are prized in culinary contexts for their delicate flavor and unusual texture, making sweetbreads a delicacy in many cuisines.

In contrast, brisket is a cut of meat from the breast or lower chest of beef cattle; it is not derived from organs. Ground meat is a general term that refers to various meats that have been finely chopped or ground, typically from a variety of muscle cuts rather than glands or organs. Steak refers to cuts taken from the muscle of cows (or other animals), and like brisket, is also not associated with organ-derived products. Thus, sweetbreads distinctly fit the description of meat derived from organ glands, making it the correct choice.
