Answer : 4. "Customer deposits"
Explanation :
Answer: D) Customer deposits Explanation: A commercial bank is a type of financial institution that accepts deposits, offers checking account services, makes business, personal and mortgage loans, and offers basic financial products like certificates of deposit (CDs) and savings accounts to individuals and small businesses. A commercial bank is where most people do their banking, as opposed to an investment bank. Commercial banks are funded through customer deposits. These banks make money by providing loans and earning interest income from those loans. The types of loans a commercial bank can issue vary and may include mortgages, auto loans, business loans and personal loans. A commercial bank may specialize in just one or a few types of loans. Customers who deposit money into these accounts effectively lend money to the bank and are paid interest. However, the interest rate paid by the bank on money they borrow is less than the rate charged on money they lend.

Answer : 4. "Methane"
Explanation :
Answer: D) Methane Explanation: Natural gas is primarily composed of methane, but also contains ethane, propane, and heavier hydrocarbons. Natural gas is a colorless, tasteless, odorless, and non-toxic gas. Because it is odorless, mercaptan is added to the natural gas, in very small amounts to give the gas a distinctive smell of rotten eggs. This strong smell can alert you of a potential gas leak. It also contains small amounts of nitrogen, carbon dioxide, hydrogen sulphide and trace amounts of water.
