The graph shows the price of a good compared to the quantity demanded.

this graph demonstrates how

the amount produced slightly changes with the price.
the amount produced greatly changes with the price.
the amount consumed slightly changes with the price.
the amount consumed greatly changes with the price.

The third alternative is correct.

This graph shows that the quantity demanded changes slightly when the price decreases. At the first moment, at the price of $ 50 the amount demanded is 15 units. After a significant price reduction, now $ 30, demand increased by only 5 units, totaling 20 units consumed. In microeconomic theory, the demand for this good is considered inelastic. A demand is inelastic when the reduction / increase in the price of the good is not accompanied by an increase / decrease in the demand for the good.
