The correct answer for why the Price Elasticity of Supply (PES) will always be positive is: **When price increases, quantity supplied increases and when price decreases, quantity supplied decreases.** This statement captures the fundamental relationship between price and quantity supplied according to the law of supply: as prices rise, suppliers are generally willing and able to produce and sell more of a good or service, and conversely, as prices fall, the quantity supplied typically decreases. This creates a positive relationship between price changes and supply responses, leading to a positive PES value.
