The vertical axis is labeled millions and ranges from 0 to 900 in increments of 100. The horizontal axis is labeled year and lists dates from 1700 to 2000 in 100-year increments. The line for population starts at 90 million for 1700 and with a slow growth rate reaches to 120 million by 1900. The line then rises with a high growth rate and reaches beyond 600 million by 2000. The line for steel consumption starts from 0 in 1860 and reaches 20 million by 1900. The line then rises with a high growth rate to reach beyond 800 million by 2000. The values used in the description are approximate.

The most appropriate response to explain the increase in steel consumption seen on the graph is:
More building construction is needed to provide for the needs of people.
This answer reflects the fact that as populations grow, especially in the 20th century, there tends to be an increased demand for infrastructure, housing, and other constructions which typically require steel.
