Which prefix means 'against'?

Explanation:
A prefix that conveys opposition or prevention is anti-. It attaches to a root to express being against or opposing the action, as in antibiotic (against bacteria) or anti-inflammatory (against inflammation). The other options don’t carry the meaning of against: tri- signals three, stenosis refers to a narrowing condition, and -oma is a suffix meaning tumor or swelling. So anti- is the correct prefix.
