The correct answer is B . A principal-protected note (PPN) is a structured debt product designed so that, subject to the terms of the note and the creditworthiness of the guarantor or issuer, the investor's original principal is protected if the note is held to maturity . CSA investor material describes a PPN as consisting partly of an investment that promises the return of the investor's original amount after the specified term, with a guarantor supporting that amount.

The second component typically provides exposure to an index, fund or other market-based investment, creating the potential for additional return. Importantly, that additional return is not guaranteed . CIRO guidance also emphasizes that principal protection is normally dependent on holding the PPN until maturity; early redemption may cause the investor to lose the protection and incur additional charges.

B is therefore the defining feature. A overstates the risk because principal protection distinguishes PPNs from direct equity ownership, although PPNs still involve liquidity, credit, complexity and opportunity-cost risks. C is incorrect because returns above principal are not guaranteed. D directly contradicts the product's defining characteristic.

Within the CIRE syllabus, PPNs fall within structured products , for which candidates must know their features, risks, returns, costs and disclosure requirements.
