C) increase the money supply
Monetarism sees careful control of the money supply as the key to maintaining a stable economy. The ideas of monetarism were first put forth by economist Milton Friedman, who believed that those in charge of the money supply in a society should focus on maintaining price stability. Having too much cash in circulation stimulates inflation. However, in regard to your particular question, during a recession prices stagnate or decrease and interest rates are forced to drop as well. Monetarists would see an increase in the money supply as a way to turn prices back upward during a recession.
I think your question means how did the discovery of gold contribute to the creation of the transcontinental railroad. There had been some movements toward westward settlement in the 1840s, but that trend accelerated dramatically with the discovery of gold in California. James Marshall's finding of gold at Sutter's Mill in California in 1848 led to a "gold rush" in the decade that followed, with 1849 seeing a huge influx of people to California. (Thus we refer to the '49ers.) The swift settlement of California added incentive to build a transcontinental railway. The Pacific Railroad Act of 1862 established the charter for doing that. The First Transcontinental Railroad was completed in 1869.
