Answer:
The correct answer is letter "A": sell their shares to other investors.
Explanation:
Closed-end funds are pools of assets that at the beginning raise a fixed amount of income thanks to an Initial Public Offering (IPO) and later on trades in a public stock exchange. Close-end funds are said to provide higher returns than open-end funds. When investors have a position with a closed-end fund, to exit it the number of shares held must be sold to another investor.
