In Microeconomics, what does supply refer to?

Option 1 -> This describes demand, not supply - it refers to what consumers want to buy.

Option 2 -> This correctly defines supply as the quantity producers are willing to sell at various prices.

Option 3 -> This is another way of describing demand, focusing on the market perspective.

Option 4 -> This is too narrow and excludes private producers who are the main suppliers in most markets.

Hence, Option 2: The total amount of goods and services which producers are willing to sell at different price -> In microeconomics, supply represents the relationship between price and the quantity that producers are willing and able to offer for sale in the market. The law of supply states that as price increases, quantity supplied typically increases (direct relationship), because higher prices make production more profitable for producers. Supply is fundamentally about sellers/producers, while demand is about buyers/consumers. -> correct
