The least reactive elements on the periodic table are found in **C. the group with helium at the top**, which corresponds to the noble gases. Noble gases such as helium, neon, and argon have filled electron shells, making them very stable and nonreactive under normal conditions. In contrast, the other groups mentioned (with fluorine, carbon, or hydrogen) contain elements that are more reactive.
