**Step 1:** Analyze the options for the purpose of XML files in Android development.

Option 1: To store user data and preferences.  
SharedPreferences uses XML internally for storage, but developers do not write XML files to store data.

Option 2: To design user interface and layout elements.  
XML files (e.g., 	exttt{activity\_main.xml}) define UI layouts with views like 	exttt{TextView}, 	exttt{Button}, and layouts like 	exttt{LinearLayout}.

Option 3: To compile Kotlin code.  
Kotlin code is compiled using the Kotlin compiler (	exttt{kotlinc}) and Gradle build system.

**Step 2:** Identify the primary purpose.  
XML is used to declaratively design the user interface and layout elements.
