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 ${}_{92}^{235}U$
(B)	Fission in a nuclear reactor	(Q)	${}_{27}^{60}Co$nucleus
(C)	$\beta$-decay	(R)	Energy production in stars via hydrogen conversion to helium
(D)	$\gamma$-ray emission	(S)	Heavy water
		(T)	Neutrino emission

(A) Nuclear fusion : In stars energy is produced by hydrogen into helium.

(B) Fission in a nuclear reactor : In nuclear reactor fission of ${}_{92}^{235}U$takes place by absorption of thermal neutrons. Heavy water is used as a moderator during this reaction.
(C) ${}_{27}^{60}Co$ particle to attain stable nucleus. It also emits $\gamma$ radians.
(D) $\gamma$-rays are emitted by ${}_{27}^{60}Co$ during fission of ${}_{92}^{235}U$ , conversion of hydrogen to helium and during decay of $U^{235}$, after absorption of neutron.
