Given below are two statements: Statement-I : Corrosion, dissolution and crystallization occur at interfaces. Statement-II : Under high vaccum of the order (10⁻⁸ ) to (10⁻⁹ ) pascal ultra clean surface of metals can't be obtained In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

Statement-I: Corrosion, dissolution, and crystallization occur at interfaces. This statement is correct. These processes are known to occur at the interfaces between different phases or materials. Statement-II: Under high vacuum of the order (10⁻⁸ ) to (10⁻⁹ ) pascal, ultra clean surfaces of metals can't be obtained. This statement is incorrect. While achieving ultra-clean surfaces can be challenging, high vacuum conditions in the range of (10⁻⁸ ) to (10⁻⁹ ) pascal can actually help in achieving cleaner surfaces by
