Correct option is B
Food will cook faster in a copper pot. Copper is an excellent conductor of heat, meaning it transfers heat rapidly and evenly. This helps in cooking food faster compared to other materials like steel, silver, or bronze. While silver is also a good conductor, it is rarely used for cooking due to its cost. Steel and bronze are less efficient in conducting heat compared to copper.
Copper has a thermal conductivity of 401 W/m·K, which is much higher than that of stainless steel or bronze.
