A 45-year-old male patient needs a kidney transplant but is incompatible with his living donor. The patient's wife, who is also willing to donate a kidney, is incompatible with him as well. However, both patients have been matched with other pairs in a paired kidney exchange program, where the donor from one pair can donate to the recipient of another pair. How does the paired exchange program work in this scenario?

The paired exchange program requires both the donor and recipient to be compatible with the transplant center's kidney transplant waiting list.

The paired exchange program allows the recipient to receive a kidney from a deceased donor instead of their living donor.

The paired exchange program works only for recipients who have matching blood types with their donors.

The paired exchange program allows the living donors to exchange kidneys with another compatible donor-recipient pair, ensuring both recipients receive a compatible kidney.
