What age group does veal come from?

Veal is sourced from newborn calves, typically those that are between a few weeks to several months old. This meat is known for its pale color and tender texture, which results from the calves' diet and the fact that they have not yet matured. The production of veal focuses on young animals primarily due to their unique quality of meat that is highly sought after in culinary applications.

The other options refer to different developmental stages of cattle that produce a variety of beef but not veal. For example, fully grown cows and young bulls produce different cuts of beef characterized by more muscle and a different flavor profile. Therefore, the distinct characteristics of veal clearly arise from using very young calves, making this answer correct.
