The notation given is a shorthand for elements, where the number following "P" indicates the atomic number (protons) and the number following "U" indicates the atomic mass. The element with the atomic number 92 (P92) is Uranium (U), and the one with a mass number of 235 (U235) is Uranium-235, which is well-known for undergoing fission. This makes option E (²³⁵U) the correct answer, as it represents Uranium-235.
