Antibiotics are chemicals produced by living organisms that kill bacteria. Which option lists antibiotics correctly?

Explanation:
Antibiotics are chemicals produced by living organisms that kill bacteria, so the option that names antibiotics is the direct match to the description. Vaccines are substances that help the immune system recognize pathogens and build immunity, not ones that directly kill bacteria. Antacids neutralize stomach acid, and hormones are signaling molecules that regulate bodily processes. That makes the term antibiotics the correct choice.
