The correct answer is B. Capital and oil rig
Step-by-step explanation:
In economics, there are four main factors of production that include land (natural resources), labor (workers that participate in production), capital (machines, tools, and buildings), and entrepreneurship (individuals that use the land, capital, and labor for profit). According to this, the one that is matched correctly is "Capital and oil rig" because an oil rig refers to a structure or building used to extract oil or natural gas and therefore this is a machine or building that is part of the production and is classified as capital.
