Answer

Brief Explanations:

Nuclear fission is a process where a heavy nucleus splits into two or more smaller nuclei. In the given options, the reaction where uranium - 235 absorbs a neutron and splits into cesium - 140, rubidium - 94 and two neutrons is a fission reaction. The other reactions are either fusion (combination of light nuclei) or radioactive decay.

Answer:

$\ce{^{235}{92}U + ^{1}{0}n\rightarrow^{140}{55}Cs + ^{94}{37}Rb + 2^{1}_{0}n}$
