Tanner is choosing between two investment options. He can invest $$500$ now and get $($guaranteed$)$ $$550$ in one year, or invest $$500$ now and get $($guaranteed$)$ $$531\mathrm{.}40$ back later today. The risk$-$free rate is $3\mathrm{.}5\%.$ Which investment should Tanner prefer?

A$.$

Neither $-$ both investments have a negative NPV$.$

B$.$

Tanner should be indifferent between the two investments, since both are equivalent to the same amount of cash today.

C$.$

$$550$ in one year, since it is $$50$ more than he invested rather than $$31\mathrm{.}40$ more than he invested.

D$.$

$$531\mathrm{.}40$ later today, since $$1$ today is worth more than $$1$ in one year.
