A. Hypertension is a contraindication to becoming a kidney donor because it can lead to further kidney damage and complicate the donor's ability to maintain kidney function after donation. B. Primary glaucoma does not prevent someone from becoming a kidney donor. C. Osteoarthritis does not interfere with the ability to donate a kidney unless there is another underlying issue that affects the function of the kidney or the donor's health. D. Amputation would not be a contraindication to kidney donation unless the donor has other health issues that affect the donation process.
