Final answer:
Stockbrokers, primarily known as 'Account executives', serve as intermediaries in the financial markets, executing trades for clients and managing client relationships. They are distinct from market makers or trader-dealers, who have broader roles in the financial sector. The correct answer is b.
Step-by-step explanation:
Stockbrokers can be referred to by several different titles, reflecting the various roles they may play in the financial markets. Generally, the term stockbroker refers to an individual or firm that acts as an intermediary between buyers and sellers of stocks, earning a commission for this service. While it's plausible for stockbrokers to act as market makers or trader-dealers, especially within firms, these roles involve additional responsibilities beyond a traditional stockbroker's scope.
In the context of the choices provided, the closest title that accurately describes a stockbroker is Account executives (Option B). Account executives handle client relationships and execute trades on behalf of their clients, aligning with the primary functions of stockbrokers. They are different from commission sellers and traders, who might not necessarily handle direct client relationships. The correct answer is b.
