The second alternative is correct.
The best title for the chart is "Factors That Affect Supply".
The supply of goods and services responds to the stimulus of the economy and the law of supply and demand, according to which supply and demand for goods and services determine market prices.
Variations in supply are explained through the concept of elasticity. The supply of a good is considered elastic when small variations in the market price are sufficient to significantly change the quantity offered. Conversely, when price changes do not significantly affect supply, we say supply is inelastic.
Another factor influencing supply is the firm's productive capacity. In the short term, the firms have a facility that limits the expansion of supply beyond installed capacity. Thus, if a firm wants to increase supply, it will need to increase its productive capacity first.
Finally, competition is a natural factor that affects supply, since it changes the price of goods and services. Firms will only provide if their cost structure makes it possible to make a profit at each price level practiced in the market.
