At the equilibrium price, the market is balanced because which of the following conditions hold true?

Explanation

Option A suggests that all goods are sold, which may not always be the case. Option B implies buyers use all their money, which is unrelated to equilibrium. Option C correctly states that quantity demanded equals quantity supplied. Option D incorrectly describes excess demand equaling quantity. Therefore, the correct answer is E, as both C and D together describe the market-clearing condition.
