The correct answer is: A. investment banking house.
An investment banking house is a financial institution that helps companies and governments raise capital by underwriting and distributing securities. They also provide advice on mergers and acquisitions, restructuring, and other financial matters.
Merrill Lynch is an investment banking house that was founded in 1914. It is one of the largest investment banks in the world, with offices in more than 40 countries. Merrill Lynch provides a wide range of investment banking services, including underwriting, sales and trading, and investment research.
A saving house is a financial institution that offers savings accounts and other deposit products. They also offer loans, such as mortgages and car loans. Saving houses are regulated by the government and are insured by the Federal Deposit Insurance Corporation (FDIC).
A saving bank is a type of savings house that is owned by its depositors. They are also regulated by the government and are insured by the FDIC. Saving banks offer a wider range of products and services than traditional savings houses, such as checking accounts, money market accounts, and certificates of deposit.
In conclusion, Merrill Lynch is an investment banking house, not a saving house or a saving bank.
