I think its c. Sex antigen

Female donor kidneys had poorer graft survival rates than male donor kidneys.
Use of cyclosporine (CsA), pretransplant transfusions, and HLA-A,B mismatches independently contributed to the poorer survival rates of female donor kidneys. A large component of the donor sex effect may have been related to CsA toxicity.
Broadly sensitized (greater than 50% PRA) recipients of first transplants had 8% lower 1-year graft survival rates when they received a female donor kidney.
Female donors between the ages of 36 and 45 years yielded significantly lower 1-year graft survival rates in recipients of both first transplants and regrafts. This may represent a special donor risk group.

you explained right.
For the successful grafting there is biases on gender, it is considered that if a female patient receive a kidney from female donor there is higher survival rate. so, sex antigen is important to consider during grafting.
The answer is not c.
