Answer: Option (a) is the correct answer.
Explanation:
When a heavy nucleus of a large element splits into small nuclei then this type of reaction is known as nuclear fission.
For example, [tex]^{235}_{92}U + ^{1}_{0}n \rightarrow ^{90}_{36}Kr + ^{143}_{56}Ba + 3^{1}_{0}n[/tex]
Energy absorbed by the nucleus of large atom causes it to split when it is striked by a neutron or a particle.
Thus, we can conclude that the statement a nucleus spontaneously splits and absorbs energy, best describes nuclear fission.
Answer: D) Nuclei combine to form a heavier nucleus, releasing energy.
