An investor wants to diversify their holdings to include real estate investment trusts.

A publicly traded REIT best satisfies the investor’s need for liquidity and relatively efficient transaction execution. Publicly traded REITs are listed on exchanges and can generally be bought and sold in the secondary market during trading hours, subject to market price fluctuations and normal trading costs. Choice D is therefore correct. Private REITs are not publicly traded and are generally less liquid, often involving restrictions on transfer and limited redemption opportunities. Non-traded REITs may be registered but not exchange-listed, and they can carry higher upfront costs, limited liquidity, and redemption limitations. Choice A is incorrect because publicly traded REITs can meet the stated objectives better than private or non-traded alternatives. The SIE outline identifies REITs as a product category and requires knowledge of listed, registered non-listed, and private REITs. It also emphasizes liquidity risk as a core investment risk. The question combines product structure with investor needs: the investor wants real estate exposure, low transaction friction, and the ability to sell quickly. Listed REITs are the appropriate structure for that objective. Reference: Section 2.1.7 Real Estate Investment Trusts; Section 2.2 Investment Risks, liquidity risk.
