B is correct. The difference between continuous compounding and daily compounding is €127,496.85 – €127,491.29 = €5.56, or ≈ €6, as shown in the following calculations. With continuous compounding, the investment earns (where PV is present value)

= €1,127,496.85 – €1,000,000  = €127,496.85.

With daily compounding, the investment earns:

–€1,000,000 =€1,127,491.29–€1,000,000=€127,491.29.      127,496-127,491=6。

分别计算连续复利，以及日复利的终值然后相减。
