Whole point of administering a SERM after breast cancer is to reduce risk of recurrence. Increased estrogen exposure is associated with increased risk of breast cancer (per FA 2019 p. 636). So you're looking for something that is an estrogen antagonist at the breast, which narrows it down to B and C right off the bat.
