Correct answer
C. a-r,t;b-p,s;c-q,t;d-r;
Step-by-step solution
Nuclear fusion : In stars energy is produced by hydrogen into helium. Fission in a nuclear reactor : In nuclear reactor fission of U 92 235 takes place by absorption of thermal neutrons. Heavy water is used as a moderator during this reaction. C o 27 60 emits β particle to attain stable nucleus. It also emits γ radians. γ -rays are emitted by C o 27 60 during fission of U 92 235 , conversion of hydrogen to helium and during decay of U 235 after absorption of neutron.
