C. Anaesthetics
D. Antipyretics

Answer

To solve the question, "Drugs which produce insensibility to the vital functions of the nervous system are known as," we will analyze the options provided and determine the correct answer step by step.

### Step 1: Understand the Question
The question asks for a specific type of drug that causes insensibility to the vital functions of the nervous system. This means we are looking for a drug that can induce a state where the nervous system's functions are diminished or blocked.

**Hint:** Focus on the definition of the terms used in the question, especially "insensibility" and "nervous system."

### Step 2: Analyze the Options
The options given are:
1. Antibiotics
2. Analgesics
3. Anesthetics
4. Antipyretics

We will evaluate each option:
- **Antibiotics:** These are drugs used to treat bacterial infections. They do not affect the nervous system's insensitivity.

**Hint:** Consider what each type of drug is primarily used for.

- **Analgesics:** These are pain-relieving drugs. They help reduce pain but do not necessarily cause insensibility to vital functions of the nervous system.

**Hint:** Think about whether these drugs affect sensation or just alleviate discomfort.

- **Anesthetics:** These drugs are specifically designed to induce insensitivity or loss of sensation, often used during surgeries to block pain and other sensations. They directly affect the nervous system's ability to perceive stimuli.

**Hint:** Recall the primary use of anesthetics in medical procedures.

- **Antipyretics:** These are drugs used to reduce fever. They do not have a direct effect on the insensitivity of the nervous system.

**Hint:** Consider the role of these drugs in treating symptoms rather than affecting sensory functions.

### Step 3: Identify the Correct Answer
After analyzing all the options, it is clear that the correct answer is **Anesthetics**. These drugs produce insensibility to the vital functions of the nervous system, making them the appropriate choice for the question.

**Final Answer:** Anesthetics

### Summary of Steps:
1. Understand the question regarding insensibility to the nervous system.
2. Analyze each option based on their definitions and uses.
3. Identify that anesthetics are the drugs that fit the description given in the question.
