Answer

To determine the classification of opiate narcotic drugs, let's analyze the options provided:

1. **Understanding Opiate Narcotics**: Opiate narcotics, also known as opioids, are substances derived from opium. They include natural opiates and synthetic versions like heroin.

2. **Analyzing the Options**:
- **(a) Analgesic**: Opiates are primarily known for their pain-relieving properties. They act on the peripheral nervous system to relieve pain, making them analgesics.
- **(b) Hypnotic**: While opiates can cause sedation, they are not primarily classified as hypnotics, which are drugs specifically used to induce sleep.
- **(c) Antihistamine**: Opiates do not have antihistamine properties. Antihistamines are used to treat allergic reactions and are not related to the effects of opiates.
- **(d) Antianxiety**: Opiates are not classified as antianxiety medications, which are specifically designed to reduce anxiety.

3. **Conclusion**: Based on the properties of opiate narcotics, the correct classification is that they are primarily **analgesics**.

**Final Answer**: (a) Analgesic
