B is correct, shown in the following table. 用NPV的功能按法如下找到第二行“CF”键，CF0=0，enter，点向下箭头在显示C01=0.0000的地方输入100,000，enter，再点向下箭头；F01=1输入C02=150,000；F02=1，C03=0；F03=1C04=0; F04=1 （0不能输入负号）C05=-10,000; F05=1输入完毕后，点击“NPV”，输入I=12，向下箭头，点击CPT，应该得到NPV结果即为203,190.5274，但是这里得到的结果是1,006,761.956。操作几次得到的都是一样的结果，请问那里可能出错了？
