Which of the following is an example of hard cheese?

Parmesan is considered a hard cheese because of its firm texture, which is achieved through the aging process. Hard cheeses are generally characterized by lower moisture content and a more concentrated flavor that develops over time. Parmesan, typically aged for a minimum of 12 months, exemplifies these characteristics, resulting in a cheese that can be grated and used as a garnish or ingredient in various dishes.

In contrast, Brie is a soft cheese with a creamy texture and a higher moisture content, making it distinct from hard cheeses. Feta is a brined cheese with a crumbly texture and is also classified as a soft cheese, often used in salads and Mediterranean dishes. Ricotta, which is a fresh cheese that is creamy and has a slightly grainy texture, is categorized as a soft cheese as well. These differences in texture and moisture content are key indicators in differentiating between cheese types.
