Equilibrium occurs when:

## The reasoning Equilibrium is that sweet spot in the market where **everyone's satisfied** — sellers have sold exactly what they wanted to sell, and buyers have bought exactly what they wanted to buy. There's no surplus (excess goods) and no shortage (unfulfilled demand). Think of it like a perfectly balanced scale: when **Supply = Demand**, the quantity producers want to sell matches the quantity consumers want to buy at a particular price. No pressure pushing the market up or down. The market is stable. At this point, there's no incentive for prices to change because the market has "cleared." ## Why the wrong options tempt you **A & B** trick you into thinking equilibrium means one side "wins" — but that creates imbalance! If supply > demand, there's surplus (goods piling up). If demand > supply, there's shortage (customers fighting for limited goods). Both situations push the market to adjust. **D** is pure distraction — zero price doesn't tell us anything about the balance between buyers and sellers. ## Quick takeaway **Equilibrium = market peace: the exact moment supply and demand shake hands at the same quantity.**
