Answer:
Easy it's B, this is because the rate at which we earn interest with only 1000$ does not keep up with the maintenance fee.
In B u get $1010 because of the interest after the first year,
In D u get $960 because if u get an annual interest of 2% from $1000 u get a total of $1020 but deduction from maintenance fee is $60 per year, Thus $1020-$60 = $960. Same explaination for the others as well.
