Answer Details

When the nucleus of a uranium atom is split into two fragments of nearly equal mass, it releases a significant amount of energy. This energy is known as nuclear energy. According to Einstein's famous equation E=mc^2, mass can be converted into energy. So, when the uranium nucleus is split, the sum of the masses of the two fragments produced is less than the mass of the original nucleus. This mass difference is converted into nuclear energy, which can be harnessed for various purposes, such as generating electricity. Therefore, the correct option is "nuclear energy released."
