The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Sedatives and Tranquillisers**: Begin by recognizing what sedatives and tranquillisers are. They are substances that have a calming effect on the body and are often used to treat anxiety and tension. 2. **Function of Sedatives and Tranquillisers**: These substances act as depressants of the central nervous system (CNS). This means they slow down brain activity and reduce excitement and pain. 3. **Effects on the Body**: Sedatives and tranquillisers lead to drowsiness or sleepiness. They lower the function of various body parts, contributing to their calming effect. 4. **Differentiating from Other Categories**: - **Stimulants**: These are substances that increase brain activity and excitement, which is the opposite of what sedatives and tranquillisers do. - **Hallucinogens**: These substances cause hallucinations and altered perceptions, which is not a characteristic of sedatives and tranquillisers. - **Pain Killers**: While sedatives may reduce pain, they do not relieve it in the same way that pain killers do. 5. **Conclusion**: Based on the above points, sedatives and tranquillisers are classified as depressants because they depress the CNS and induce calmness. **Final Answer**: (b) Depressants ---
