All else equal, bond price volatility is greater for ________.

A) higher coupon rates
B) lower coupon rates
C) shorter maturity

Higher coupon rates make bonds less sensitive to interest rate changes, resulting in lower price volatility. Maturity and default risk also affect bond price volatility, but the question only asks for the best choice, which is option B.
