The correct answer is C. There were limited resources for people if they found themselves in hard times.
The creation of the social programs we know in America today (like Social Security, Medicare, Medicaid, etc.) were not created until President Franklin D. Roosevelt entered office in 1933. Before this time, individuals who fell on hard times would usually look to a church or other private charity to help. However, these types of charities were extremely limited at this time. The inability for private charities to help everyone was mainly due to the Great Depression that began in America after the Stock Market Crash of 1929.

Congress is checked by the Supreme Court through the power of judicial review.
Judicial review is a power that the Supreme Court possesses thanks to the Marbury vs. Madison case. Judicial review allows the Supreme Court to rule on whether laws made by Congress are constitutional or unconstitutional. Any law passed by Congress that the Supreme Court thinks violates the US Constitution immediately becomes void. This ensures that the Supreme Court can get rid of any law made by Congress that may violate a citizens rights.
