Step 1:
Let's solve this step by step:

Step 2:
: Understanding Equilibrium

- In economics, equilibrium is the point where supply and demand curves intersect - At equilibrium, the quantity supplied equals the quantity demanded - The equilibrium price is where the supply and demand curves cross

Step 3:
: Defining Shortage

- A shortage occurs when the quantity demanded exceeds the quantity supplied - On a graph, this means the quantity is BELOW the equilibrium quantity - Shortage appears as the horizontal distance between the quantity demanded and quantity supplied at a price ABOVE the equilibrium price

Step 4:
: Defining Surplus

- A surplus occurs when the quantity supplied exceeds the quantity demanded - On a graph, this means the quantity is ABOVE the equilibrium quantity - Surplus appears as the horizontal distance between the quantity supplied and quantity demanded at a price BELOW the equilibrium price

Step 5:
: Analyzing the Given Options

- Option A: Incorrect. Shortage is NOT above the equilibrium price - Option B: Incorrect. Surplus relates to quantity, not price - Option C: Incorrect. Shortage is not simply below the demand curve - Option D: Correct. Surplus is the area above the supply curve where quantity supplied exceeds quantity demanded

Final Answer

Surplus is the area above the supply curve.
