The correct answer to the question is:
A) prescription
Explanation:
1. A prescription is a written order from a doctor for a specific medication or treatment.
2. In this context, the doctor gave the person a prescription for an antibiotic, indicating the specific antibiotic and dosage needed to treat the illness.
3. A medication is a broader term that can refer to any substance used to treat an illness, while a prescription specifically refers to the doctor's order for that medication.
4. A drugstore is a place where medications can be purchased, but in this case, the person received a prescription to obtain the antibiotic.
5. A condition refers to a state of health or a particular illness, which is not the same as a prescription for a medication.
