A metalloid rod 2 cm in diameter is used as a heating element. The thermal conductivity is 370 J/s-m²-°C. The surface temperature is maintained at 200°C. For the center of the rod not to exceed 500°C, the maximum volumetric heat generation rate within the metallic rod in J/s-m³ must be A. 4,440,000,000 B. 5,130,000,000 C. 6,930,000,000 D. 2,040,000,000
