What is the definition of a well-done steak?

A well-done steak is defined as being fully cooked with no pink remaining in the center. The cooking process has brought the internal temperature of the steak to a level that ensures it is fully cooked, resulting in a firm texture and a brown or gray appearance throughout. For diners who prefer a well-done steak, the absence of any pink signifies that the meat has been cooked thoroughly, making it safe to eat according to food safety standards.

In contrast, the other options describe various levels of doneness: a slightly pink center indicates a medium-rare or medium steak, while a red center suggests a rare steak. A bright red throughout is typical of a rare steak as well, emphasizing the difference in cooking techniques and the resulting textures and flavors associated with each doneness level. Thus, option A accurately captures the essence of what is meant by a well-done steak.
