Answer

To solve the question regarding Veronal and Luminal, which are derivatives of barbituric acid, we need to identify their classification and characteristics. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Compounds
Veronal and Luminal are both derivatives of barbituric acid.

### Step 2: Classify Barbiturates
Barbiturates, including Veronal and Luminal, are classified as tranquilizers. Tranquilizers are medications that help to calm the nervous system and are often used to treat anxiety, depression, and other mental health issues.

### Step 3: Understand the Function of Tranquilizers
Tranquilizers work by acting on the central nervous system (CNS). They induce relaxation, reduce anxiety, and can promote sleep. However, they can also be addictive and may have sedative effects.

### Step 4: Eliminate Incorrect Options
- **Non-Narcotic Analgesic**: This refers to pain relievers that do not require a prescription and do not have addictive properties, which does not apply to barbiturates.
- **Anti-Allergic Drug**: These are typically antihistamines and are not related to barbiturates.
- **Neurologically Active Drug**: While barbiturates do affect the nervous system, the primary classification of Veronal and Luminal is as tranquilizers.

### Step 5: Final Conclusion
Based on the classification and function of Veronal and Luminal, the correct answer to the question is that they are tranquilizers.

### Answer:
Veronal and Luminal are derivatives of barbituric acid which are classified as **tranquilizers**.
