Match the nuclear processes given in column I with the appropriate option(s) in column II.
Column I Column II
A. Nuclear fusion P Absorption of thermal neutrons by U92235U 92235
B. Fission in a nuclear reactor Q Co2760Co 2760 nucleus
C. β\beta -decay R Energy production in stars via hydrogen conversion to helium
D. γ\gamma -ray emission S Heavy water
T Neutrino emission

Options

  1. Aa-q,r,s,t;b-s,t;c-r;d-q,r,s,t;
  2. Ba-t;b-s;c-q;d-q,r,s,t;
  3. Ca-r,t;b-p,s;c-q,t;d-r;
  4. Da-q,r,s,t;b-r;c-s;d-t;

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 U92235U 92235 takes place by absorption of thermal neutrons. Heavy water is used as a moderator during this reaction.
Co2760Co 2760 emits β\beta particle to attain stable nucleus. It also emits γ\gamma radians.
γ\gamma -rays are emitted by Co2760Co 2760 during fission of U92235U 92235 , conversion of hydrogen to helium and during decay of U235{U}^{235} after absorption of neutron.
