Perpetuity receiving, discount, payments, decided

toocfatoo

In 10 years you will begin receiving $155 dollars per year in perpetuity from your grandparent's family trust fund (first payment is exactly 10 years from today). You consider these payments essentially risk free and have decided to discount them at a constant risk free rate of 6.5%. What is the present value today of these future cash flows?

a. 1353
b. 2385
c. 1270
d. 146

I am thinking it's c.
Please help.
