Which of the following is an analgesic?

Options

A. Ranitidine
B. Aspirin
C. Penicillin
D. None of these

Answer

To determine which of the following options is an analgesic, we need to understand what an analgesic is and evaluate each option accordingly.

### Step-by-Step Solution:

1. **Define Analgesic**: An analgesic is a type of medication that is used to relieve pain. It does not necessarily cure the underlying issue but helps in managing the pain.

2. **Evaluate the Options**:
- **Option 1: Ranitidine**:
- Ranitidine is classified as an antacid. Antacids are used to neutralize stomach acid and alleviate symptoms of acidity, such as heartburn and indigestion. Therefore, it does not function as an analgesic.

- **Option 2: Aspirin**:
- Aspirin is a well-known analgesic. It is used to relieve pain, reduce inflammation, and lower fever. Its chemical structure includes acetylsalicylic acid, which is effective in pain relief, making it an analgesic.

- **Option 3: Penicillin**:
- Penicillin is an antibiotic, which is used to treat bacterial infections. It does not relieve pain and therefore is not classified as an analgesic.

- **Option 4: None of these**:
- This option implies that none of the previous options are analgesics. However, since we have identified that aspirin is indeed an analgesic, this option is incorrect.

3. **Conclusion**: Based on the evaluation of the options, the correct answer is **Aspirin**, as it is the only medication listed that functions as an analgesic.

### Final Answer:
The analgesic among the options provided is **Aspirin**.
