A surrogate outcome in a clinical trial is a measure of effect of a specific treatment that may correlate with a real clinical endpoint but does not necessarily have a guaranteed relationship. The surrogate endpoint is often used in clinical trials as it may be measured more easily or more rapidly than the clinical endpoint.

In the context of a clinical trial comparing mastectomy and chemotherapy in the treatment of breast cancer, a surrogate outcome could be the tumor grade. The tumor grade is a measure of the aggressiveness of the cancer, and changes in the tumor grade could potentially indicate the effectiveness of the treatment.

So, the best answer would be:

c. Tumor grade
