She can borrow at 7% APR, compounded monthly. Assuming that the oven will be used for five years, should she purchase the oven or should she lease it? O A. Buy, since the present value (PV) of the lease is $32,108 more than the cost of the oven. O B. Lease, since the present value (PV) of the lease is $12,224 less than the cost of the oven. O C. Lease, since the present value (PV) of the lease is $8642 less than the cost of the oven. OD. Lease, since the present value (PV) of the lease is $2212 less than the cost of the oven
