What was the significance of the Securities and Exchange Commission?

A) The Securities and Exchange Commission marked a departure from the legislation of previous presidencies in that it operated entirely at the state level and received little federal oversight so that the federal government could focus on the creation of jobs.
B) The Securities and Exchange Commission took away the requirement that all corporations that offer stock for public sale disclose the relevant information about the company, which would in turn make buyers of stock less confident about their purchases and purchase less.
C) Whereas there had been little government oversight of the stocks and bonds industry prior to the Great Crash of 1929, the Securities and Exchange Commission was one of the first major pieces of federal legislation involving governance of the issuance and trading of stocks and bonds.
D) Because Prohibition had been so effectively enforced and had resulted in the exchange of other nonalcoholic goods to replace alcohol, the Securities and Exchange Commission reinstated Prohibition temporarily until the state of the economy was back on track.
E) The Securities and Exchange Commission focused on raising the wages of government workers to make such jobs more appealing to those who were struggling economically due to the Depression but who refused to work for the government out of principle.
