请问C为什么错？没看懂
还是没有理解这道题，我觉得只能说最后到maturity的时候，没有capitgain tax，因为amortize到每年计算interest income tax了，但是到期的capitgain仍然是750，不能说到期的capitgain是0.
The originissue scount w$750 when he buys this bon The capitgain is $750 maturity. C is correct. Accorng to the originissue scount tprovision, the capitgain whiis the fferenbetween the prianthe pvalue nee to average amortizein every tyear’s interest income until the maturity te. So, in this case, the capitgain is $2,000- 1,250 = $750, annee to average amortizefor 15 years, it means eatyear’s amount is $750/15 = $50. The investor still nee to p$1250 for this bonthe beginning without recing the capitgain. So, C is least likely to true. 付1250是初始金额，和capitgain有什么关系？
