Answer

B

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., \texttt{activity_main.xml}) define UI layouts with views like \texttt{TextView}, \texttt{Button}, and layouts like \texttt{LinearLayout}.

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

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