Assuming that the final particles in each case are more stable than the initial particles, which of the statements regarding fission and fusion reactions is true? both fusion and fission can release or absorb energy. both fusion and fission absorb energy. fusion releases energy and fission absorbs energy. fusion absorbs energy and fission releases energy. both fusion and fission release energy.

Explanation:

Fission means breaking or splitting i.e. Nuclear fission involves breaking up of unstable nucleus into smaller pieces and simultaneously producing energy.  

Fusion means joining of different elements to form a unified whole. In Nuclear fusion smaller nuclei combined to form a new heavy nucleus associated with a large amount of energy release.

Thus nuclear Fusion and fission can release Energy.
