The electron configuration belongs to Thorium (Th), which has 90 electrons. The configuration can be broken down as [Rn] (86 electrons), 7s2 6d1 (3 electrons), 5f2 (2 electrons), and 4s2 4p0 (2 electrons). None of the other choices (Rf, Sg, Pa) have 90 electrons in their ground-state configurations.
