Which of the following services will be provided by a full-service broker but not by a discount broker?
I. Research of potential investment opportunities
II. Purchase and sale of stock at your request
III. Recommendation of investments
a. I and III
b. II only
c. III only
d. I, II, and III

A full-service broker shines by offering personalized guidance and tailored investment strategies, making them particularly beneficial for novice investors or those seeking comprehensive financial planning. They will conduct thorough research and make investment recommendations, providing insights that can help navigate complex markets.

On the other hand, discount brokers primarily serve to facilitate trades without extensive advisory services. While they efficiently execute purchase and sale orders, they typically do not provide the in-depth research or personalized recommendations that full-service brokers offer, which is why option a. I and III is a solid choice.
