Answer:
C. The opportunity to make money by selling your property in the future.
D. The opportunity to save money by not making a down payment.
Step-by-step explanation:
Option A is not an opportunity cost of choosing to buy a house instead of renting as it is possible to make changes to a rented living space as well, but the opportunity cost would be the money spent on renovations or upgrades instead of investing it in other ways. Option B is not an opportunity cost either, as renters may also need to spend time and effort on regular maintenance of the property they are renting.
