To determine the kind of medicine that aspirin is, we can break down the options and examine the characteristics of each one:

A. Over-the-counter analgesic: An analgesic is a type of medicine used to relieve pain. Over-the-counter refers to medications that can be purchased without a prescription from a healthcare professional. So, aspirin could be considered an over-the-counter analgesic since it is commonly available in stores without the need for a prescription.

B. Prescription analgesic: Prescription analgesics, on the other hand, are medications that require a prescription from a healthcare professional in order to be obtained. Since aspirin can be purchased without a prescription, it is not a prescription analgesic.

C. Over-the-counter antibiotic: Antibiotics are medications used to treat bacterial infections. However, aspirin is not an antibiotic, so the answer is not C.

D. Prescription antibiotic: As mentioned above, aspirin is not an antibiotic. Therefore, it is also not a prescription antibiotic.

Based on the explanations above, the correct answer is A. Aspirin is an over-the-counter analgesic.
