Answer: B. Only conclusion II follows

Answer: (B) Only conclusion II follows
Explanation:
• Statement 1 and 2 create nested circles: Squares ⊂ Rectangles ⊂ Polygons.
• Conclusion I is false because there can be many polygons (like hexagons or pentagons, or even rectangles that aren't squares) outside the square circle.
• Conclusion II is completely true because the entire Squares circle is trapped deep inside the massive Polygons circle.
