The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question is asking about the type of lipids that provide insulation to nerve fibers. 2. **Identifying the Structure**: In the nervous system, nerve fibers are covered by a protective layer known as the myelin sheath. 3. **Role of Myelin Sheath**: The myelin sheath is crucial for the proper functioning of nerve fibers as it insulates them, allowing for faster transmission of electrical signals. 4. **Components of Myelin Sheath**: The myelin sheath is primarily composed of lipids and proteins. Among these lipids, one important type is glycolipids. 5. **Defining Glycolipids**: Glycolipids are molecules that consist of a carbohydrate (sugar) attached to a lipid. They play a significant role in the structure of the myelin sheath. 6. **Conclusion**: Therefore, the lipids that insulate the nerve fibers are glycolipids. 7. **Final Answer**: The answer is option D: Glycolipids. ---

Assertion : Myelin sheath insulates the nerve fibre and prevents its depolarisation. Reason : Nerve impulses are conducted more rapidly in non-myelinated nerve fibres than in myelinated ones.
