</LinearLayout>
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Post" />
</LinearLayout>

Answer options

• A. An edit text to the left of a text view and a button beneath it
• B. An edit text to the right of a text view and a button to the right of the text view
• C. An edit text to the right of a text view and a button beneath them
• D. A text view, an edit text beneath it and the button beneath the edit text

Correct answer: C

Explanation

The correct answer is C because the XML structure indicates that the EditText is positioned to the right of the TextView within a horizontal LinearLayout, with the Button located below them in the vertical LinearLayout. Options A and D are incorrect as they misplace the Button or the EditText relative to the TextView, and option B incorrectly describes the layout by placing the Button to the right of the TextView.
