Answer: C. Agricultural technology.
Step-by-step explanation:
The Morrill Land-Grant Act was signed into law by President Abraham Lincoln on July 2, 1862. It ordered the creation of land-grant colleges to support the new state agricultural colleges. The Congress allowed each state in the Union to select undeveloped public land and either sell it or use it for profit, so the proceeds can be applied to build at least one college for agriculture and mechanical arts.
