To arrange the curves from **most ductile to least ductile**, we look at the strain at fracture (how far the curve extends on the x-axis). The curve which reaches the farthest on the x-axis (strain) before fracturing is the most ductile. From the graph: - **B** has the highest strain before fracture (most ductile) - **A** is next - **C** has the lowest strain before fracture (least ductile) So, the correct order is **B, A, C**. However, the answer currently selected is **A, B, C**, which is incorrect. The correct answer to select is **B, A, C**.
