Answer
FALSE: Some non-metals such as graphite conduct electricity
Explanation
This question asks if the statement "A material which conducts electricity MUST be a metal" is true or false. Here, The understanding of basic physics is important to answer the question correctly. While it’s true that metals are generally good conductors of electricity due to their free moving delocalized electrons; however, they are not the only materials that can conduct electricity. Some non-metals, such as graphite or doped semiconductors, can also conduct electricity. Therefore, the statement "A material which conducts electricity MUST be a metal" is incorrect because it omits the non-metals that can also conduct electricity.
