Based on the diagram and information, which statement best describes the fission reaction shown?

To begin a fission reaction, a neutron is shot at high speed into the nucleus of an atom of Uranium-235. This process releases a large amount of energy contained within the nucleus. The diagram above illustrates this process as well as possible by-products.

Based on the diagram and information, which statement best describes the fission reaction shown?
A . The nucleus of Uranium-235 absorbs a neutron and gets bigger.
B . The nucleus of Uranium-235 absorbs energy and gets smaller.
C . The nucleus of Uranium-235 splits into smaller nuclei and releases energy.
D . Two nuclei of Uranium-235 combine and release energy.
E . Three neutrons combine and release energy.
