Answered by GPT-4o mini
The least reactive elements on the periodic table are found in **Option A**: the group with helium at the top, which corresponds to the noble gases. These elements, including helium, neon, argon, krypton, xenon, and radon, are known for their low reactivity due to having a full valence shell of electrons.
