The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Trilamellar Model**: The trilamellar model describes the structure of the cell membrane. It suggests that the membrane consists of a fluid core of lipidic substances that is sandwiched between two layers of phospholipids. 2. **Components of the Model**: In this model, the phospholipid bilayer has hydrophilic (water-loving) head groups that are oriented towards the aqueous environment, while the hydrophobic (water-fearing) tails face inward, away from water. 3. **Role of Proteins**: The model also indicates that water-soluble globular proteins are associated with the membrane, interacting with the hydrophilic heads of the phospholipids. 4. **Historical Context**: The trilamellar model was proposed in the year 1935. 5. **Identifying the Proposers**: The scientists who proposed this model are Hugh Davson and James Danielli. 6. **Final Answer**: Therefore, the trilamellar model was proposed by Davson and Danielli in 1935. ---
