Final answer:
Statement C is not true of REITs; while they are an easy way to invest in real estate and help diversify a portfolio, they are not 'very low risk' investments due to market risks.
Step-by-step explanation:
Among the statements provided about REITs, which stands for Real Estate Investment Trusts, the one that is not true is C) They are a very low risk investment. REITs do provide an easier way to invest in real estate, as they can be bought and sold on major stock exchanges, and they are a way to diversify a portfolio since they invest in various real estate assets, often commercial. However, like any investment, they come with risks, including market fluctuations and changes in interest rates, which can affect the performance of real estate investments. Therefore, while they can be part of a diversified portfolio, they should not be considered 'very low risk' investments.
