Preferred stock is generally less risky than common stock because preferred shareholders usually have preferential rights to dividends and assets before common shareholders. One important protection is that preferred dividends are often cumulative. If the organization cannot pay dividends in one period, cumulative preferred dividends must be paid in arrears before common shareholders receive dividends. This gives preferred shareholders a stronger claim on future distributions. Option A is incorrect because common stock does not normally pay dividends as a fixed percentage of face value. Option B is wrong because preferred stock, not common stock, has priority over earnings and assets. Option D may describe yield behavior but does not explain reduced risk. Therefore, cumulative dividend preference makes Option C correct.
