The correct answer is D. Land
Step-by-step explanation:
In economics, land is one main factor of production and includes natural resources that can be used to make products, for example, wood can be used to made furniture or fruits can be used to produce juice, jam, and similar. Also, these resources are classified into renewable and nonrenewable depending on whether they are abundant and replenish in a short time. Oil is considered part of the land factor because this is a non-renewable resource that is used to produce goods such as fuels or plastic. Therefore, if new oil reserves are discovered there is an increase in land supply because more natural resources are available to produce goods.
