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
  $A \rightarrow (R, T); B \rightarrow (P, S); C \rightarrow (P, Q, R, T); D \rightarrow (P, Q, R, T)$
• B
  $A \rightarrow (R, S); B \rightarrow (P, T); C \rightarrow (P, Q, R, S); D \rightarrow (P, Q, R, S)$
• C
  $A \rightarrow (R, S); B \rightarrow (P, Q); C \rightarrow (P, Q, R, S); D \rightarrow (P, Q, T, S)$
• D
  $A \rightarrow (P, T); B \rightarrow (Q, S); C \rightarrow (Q, R, S, T); D \rightarrow (P, R, S, T)$
