The correct answer is (D) 1500°C.
The melting point of pure iron is approximately 1538°C (2800°F). The melting points of common metals are relatively high compared to typical ambient temperatures.
Options (A) 25°C and (B) 37°C are typical room and body temperatures, far too low for the melting point of a metal like iron. Option (C) 500°C is also too low; this might be closer to the melting point of certain alloys or other materials, but not iron. Option (D) 1500°C falls within the correct range for the melting point of iron. Steel, an alloy of iron and carbon, has a melting point that is typically lower than pure iron but still in the range of 1370–1530 °C, depending on the composition.
