- Land
- Labor
- Capital
- Entrepreneurship
<h3>Land </h3>
- This refers to all the natural resources that are available to be used in the production of goods.
- These natural resources includes raw materials from the ground, non-renewable resources such as petroleum and renewable resources such as timber.
- The income or reward earned from land as a factor of production is rent.
<h3>Labor </h3>
- This refers to the manpower or work done by human beings.
- The value of labor depends on the skills, education and motivation of workers.
- The reward for labor as a factor of production is wages and salaries.
<h3>Capital </h3>
- This refers to the capital goods, that is, man-made objects that are used for production of goods and services such as machinery, equipment and chemicals.
- They also include industries and commercial buildings.
- The reward or income earned from capital goods is interest

D is the correct answer
As explanation: A Supreme Court justice is appointed for life. This means that their rulings are not bound to traditional elected politics in the way that elected judges are responsible to voters. Judges agree to the doctrine of stare decisis, which refers to letting the decision stand or following precedent. This enables a smooth continuity when it comes to American law and ensures that modern law is based on small clarifications instead of wild and unpredictable shifts.
Alexander Hamilton would be the correct answer
