An over-the-counter drug is sold legally without a doctor's prescription.

• A. Sold with a doctor's prescription
• B. Always requires pharmacist approval.
• C. A medicine sold legally without a doctor's prescription
• D. Illegal and unsafe

Answer: (C)

Over-the-counter drugs are medicines that have been evaluated for safety and effectiveness and are labeled for use without a doctor's prescription. They can be bought legally in stores as long as you follow the directions on the label. This is why the correct option is the one that states a medicine is sold legally without a doctor's prescription. The other statements don’t fit: needing a prescription is the opposite of OTC, requiring pharmacist approval is not a mandatory condition for all OTC products (a pharmacist can help, but you don’t need one to purchase), and calling it illegal and unsafe ignores that these drugs are specifically approved for safe, non-prescription use when directions are followed. Remember, even without a prescription, misuse or drug interactions can cause harm, so read labels and consult a pharmacist or doctor if unsure.
