Which of the following defines a brokerage house?

The definition of a brokerage house aligns well with the notion described in option B, which is about employing analysts to research businesses for investors. Brokerage houses serve as intermediaries between buyers and sellers in financial markets, facilitating the purchase and sale of securities like stocks and bonds. They often provide valuable research and analysis about various investment options, helping clients make informed decisions based on market trends and the performance of different companies.

This ability to research and analyze different investments is a crucial function of brokerage houses, as it distinguishes them from other types of financial institutions. While brokerage houses may also support transactions involving government securities or provide other financial services, their primary role is broader and focuses on various securities and investment options available in the market. Thus, employing analysts to conduct fundamental and technical research for investors is a core characteristic of what a brokerage house does, making this definition accurate.
