which of the following is true about supply of land?

Analyze the question: It asks which statement is true about the supply of land in economics.

Concept: Land is a "gift of nature". In economics, the total supply of land (the physical surface area available) is perfectly inelastic, meaning it is fixed. It cannot be increased or decreased by changes in price or demand. (Individual uses of land, such as farmland versus housing, can shift, but total land stays fixed.)

Checking each option:

• A. Higher in urban than rural areas: False. Rural areas generally have more available land, and urban land is scarcer.
• B. Varies with time: False. Total land supply doesn't change as time passes. (Land reclamation is minor and doesn't change the general principle.)
• C. Rises with demand: False. Land supply does not respond to demand. When demand rises, only the price (rent) rises.
• D. Is fixed: True. Land has a fixed total supply, so its supply curve is a vertical line (perfectly inelastic).

Tip: Remember "Land = Fixed = Vertical supply curve". If you see "gift of nature" or "perfectly inelastic" in a land question, the answer is usually about its fixed supply.
