The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Seed Germination**: Seed germination is the process by which a seed develops into a new plant. This involves several physiological changes within the seed. 2. **Role of Seed Coat**: The seed coat protects the seed and must rupture for the seedling to emerge. The rupture of the seed coat is a crucial step in the germination process. 3. **Imbibition Process**: The first step in seed germination is imbibition, which is the physical absorption of water by the seed. When seeds absorb water, they swell and create internal pressure. 4. **Water Absorption**: As the seed absorbs water, it leads to a massive increase in internal pressure. This pressure is critical as it pushes against the seed coat. 5. **Rupture of Seed Coat**: The increased internal pressure from the absorbed water eventually causes the seed coat to rupture, allowing the embryo (radicle and plumule) to emerge. 6. **Conclusion**: Therefore, the seed coat ruptures due to the massive imbibition of water during the germination process. **Final Answer**: The correct answer is **massive imbibition of water**. ---
