Study the below graph which shows price floor set by government. Excess supply is denoted by?

Answer & explanation
Correct answer: option 3
The correct answer is option 3: qf to qf’

But when the government imposes a floor higher than the equilibrium price at pf , the market demand is qf whereas the firms want to supply q’f , thereby leading to an excess supply in the market equal to qf q’f.
