Equilibrium in a market is said to be reached if:

Equilibrium in a market occurs when the quantity of a good or service demanded by consumers equals the quantity supplied by producers. This balance indicates that the market is functioning efficiently, with neither a surplus nor a shortage.

High supply and high demand suggest that there is a strong interest in the good or service, and producers can meet this interest. When both supply and demand are high, the market is likely to reach an equilibrium price where most consumers can purchase the item without excess inventory sitting unsold. This scenario also supports stable pricing as supply meets the demand effectively.

In contrast, the other options illustrate scenarios that do not lead to equilibrium. Low supply with high demand creates a shortage, potentially driving prices up. High supply with low demand results in a surplus, leading to excess inventory and possibly lowering prices. Zero supply and zero demand represents a complete market failure where no transactions take place, which also does not represent equilibrium in any sense. Understanding these dynamics is essential for effective market analysis and property management.
