The correct answer is B. Price.
Elasticity of supply is a measure of how much the quantity supplied of a good
or service changes in response to a change in its price. It is calculated as the percentage change in quantity supplied divided by the percentage change in price.A good with elastic supply is one in which the quantity supplied changes by a large percentage in response to a small percentage change in price. A good with inelastic supply is one in which the quantity supplied changes by a small percentage in response to a large percentage change in price.
The price of a good is one of the most important factors that affects the quantity supplied of that good. When the price of a good increases, producers are willing to supply more of that good, and when the price of a good decreases, producers are willing to supply less of that good.
The other factors that can affect the quantity supplied of a good include the cost of production, the state of technology, and the prices of other goods. However, the price of a good is usually the most important factor that affects the quantity supplied.
Here is a brief explanation of each option:
- Option A: Demand. Demand is the willingness and ability of buyers to purchase a good or service. It is not a factor that affects the quantity supplied of a good.
- Option B: Price. Price is the amount of money that buyers are willing and able to pay for a good or service. It is the most important factor that affects the quantity supplied of a good.
- Option C: Cost of production. The cost of production is the amount of money that producers spend to produce a good or service. It is a factor that affects the quantity supplied of a good, but it is not as important as the price of the good.
- Option D: State of technology. The state of technology is the level of knowledge and skills that producers have about how to produce goods and services. It is a factor that affects the quantity supplied of a good, but it is not as important as the price of the good.
