Livestock is a renewable and primary commodity. Renewable commodities are those that can be replenished over time through natural processes. Livestock, being a product of agricultural activities, falls under this category. They are bred and raised, and their population can be replenished over time, making them renewable. Primary commodities, on the other hand, are commodities that are traded in their raw, unprocessed form. Livestock, being traded in their live form without any processing, are considered primary commodities. Therefore, livestock is both a renewable and a primary commodity.

Choice A is incorrect. Oil is an extractable commodity, not renewable. It is formed from the remains of ancient marine plants and animals, a process that takes millions of years. Therefore, it cannot be replenished in a short period of time.

Choice B is incorrect. Copper is also an extractable commodity as it comes from the earth's crust and cannot be renewed once extracted.

Choice D is incorrect. Gasoline, although derived from oil which makes it primary in terms of processing stage, it's not renewable because its source (oil) isn't renewable.
