You would choose exact interest. 200 days is a smaller fraction of 365 days than it is of 360 days, so the effective rate would be lower for exact interest.

The amount of interest is

... I = Prt = 71,500·0.09·200/days

The larger value you choose for days, the smaller the interest amount will be.
