Answer:
The correct answer is letter "B": They treat income as "passed through" to the investor for tax purposes.
Step-by-step explanation:
A mutual fund is a pool of assets that allow investors to diversify their portfolios, thus, reduce the risk inherent. Mutual funds are usually managed by professionals which also increases the chances of making a profit. Small investors can access to mutual funds but must consider the fees that should be paid to keep their investments.
In front of revenue, just like with any other investment, mutual funds are taxed out of the investors' pockets. They are not pass-through assets such as mortgage-backed securities (MBS).
