Explanation:

• Option A (Livestock) is correct because commodities include both 'hard' commodities (e.g., mined or extracted resources like copper or oil) and 'soft' commodities (e.g., grown resources like livestock, grains, and cash crops such as coffee). Livestock falls under the 'soft' commodities category.

• Option B (Timberland) is incorrect because timberland is classified as a separate component of natural resources, not a commodity. Natural resources encompass commodities, agricultural land, and timberland.

• Option C (Agricultural land) is incorrect for the same reason as Option B. Agricultural land is part of natural resources but is distinct from commodities, which are the actual physical goods traded in markets.
