Two nuclear processes are proposed: Process I:

^{235}_{92}\text{U}\;\rightarrow\;^{141}_{56}\text{Ba}+^{92}_{36}\text{Kr}+2\,n

Process II:

^{4}_{2}\text{He}+^{4}_{2}\text{He}\;\rightarrow\;^{8}_{4}\text{Be}

Using only the qualitative features of the binding-energy-per-nucleon curve, which statement about the net energy change in these processes is correct? a) Both I and II release energy. b) Both I and II absorb energy. c) I releases energy, II absorbs energy. d) I absorbs energy, II releases energy.
