解释：
A is correct. Exceptions to the maturity effect are rare and occur only for low-coupon (but not zero-coupon) long-term bonds trading at a discount.
B is incorrect because the maturity effect holds for bonds that have short maturities and high coupons.
C is incorrect because the maturity effect always holds on bonds priced at a premium above par value.
