The correct Answer is:
To solve the question, we need to analyze both statements carefully: **STATEMENT - 1**: Osmosis involves movement of solvent molecules from lower concentration to higher concentration. **STATEMENT - 2**: Solutions having the same osmotic pressure are called isotonic solutions. ### Step-by-Step Solution: 1. **Understanding Osmosis**: - Osmosis is the process where solvent molecules move through a semi-permeable membrane from a region of lower solute concentration (higher solvent concentration) to a region of higher solute concentration (lower solvent concentration). - Therefore, **Statement 1** is correct because it accurately describes the direction of solvent movement in osmosis. 2. **Understanding Isotonic Solutions**: - Isotonic solutions are defined as solutions that have the same osmotic pressure. This means that when two solutions are isotonic, there is no net movement of solvent molecules between them when separated by a semi-permeable membrane. - Hence, **Statement 2** is also correct as it correctly defines isotonic solutions. 3. **Evaluating the Relationship**: - While both statements are true, we need to determine if Statement 2 serves as a reason or explanation for Statement 1. - Statement 1 describes the process of osmosis, while Statement 2 describes a condition of solutions (isotonicity). They are related concepts but do not explain each other directly. 4. **Conclusion**: - Both statements are true, but Statement 2 does not provide a correct explanation for Statement 1. - Therefore, the correct answer is that both statements are true, but Statement 2 is not the correct explanation for Statement 1. ### Final Answer: **B**: Both statements are true, but Statement 2 is not the correct explanation for Statement 1. ---
