Cast iron is least likely to cause the brownies to burn due to its slower and more even heat conduction compared to glass, aluminum, and copper. Hence option c) a cast iron pan.
In the context of baking brownies and avoiding burning the bottoms, the pan made of cast iron is least likely to cause the brownies to burn. This is due to cast iron's relatively slower heat conduction in comparison to the other materials mentioned: glass, aluminum, and copper. These materials conduct heat more quickly, which could lead to the bottoms of the brownies getting too hot and burning before the rest of the brownie is properly baked.
Each material's thermal conductivity plays a significant role here. Copper and aluminum have high thermal conductivity, which means they transmit heat rapidly, making them more susceptible to burning the bottoms of baked goods. Glass, while being a slower conductor than copper and aluminum, can still lead to burning due to the possibility of hot spots. Cast iron, however, has a lower thermal conductivity and heats up more evenly but slowly, reducing the risk of burning.

The least likely pan to cause burning of the bottoms of brownies is a glass pan, as it conducts heat evenly and retains it well. Aluminum, cast iron, and copper pans tend to conduct heat more efficiently, which can lead to burning. Therefore, for the best results, a glass pan is recommended for baking brownies.
