B A student turns a hotplate to warm and stands 4 feet way. The student observes how long it takes for their hands to feel warmth in the air.A student turns a hotplate to warm and stands 4 feet way. The student observes how long it takes for their hands to feel warmth in the air.
C A student sets a large pot of water halfway on a hotplate set to warm and halfway on a stack of cold bricks. The student observes what happens as they add drops of food coloring.A student sets a large pot of water halfway on a hotplate set to warm and halfway on a stack of cold bricks.

The best demonstration of heat transfer through conduction among the provided options is:
A: A student heats the tip of a metal rod on a hotplate set to warm. The student observes how long it takes for the opposite end of the metal rod to feel warm.
This scenario illustrates conduction as heat is transferred through direct contact from the hot end of the metal rod to the cooler end, demonstrating the process of thermal energy moving through a solid material.
