Q. Which one of the following nuclear reaction is a source of energy in the sun?
A) $\ _{4}Be^{9} + \ _{2}He^{4} \rightarrow \ _{6}C^{12} + \ _{0}n^{1}$
B) $\ _{2}He^{3} + \ _{2}He^{3}{\rightarrow \ }_{2}He^{4} + \ _{1}H^{1} + \ _{1}H^{1}$
C) $\ _{56}Ba^{144} + \ _{36}Kr^{92} \rightarrow \ _{92}U^{235} + \ _{0}n^{1}$
D) $\ _{26}Fe^{50} + \ _{48}Ca^{112} \rightarrow W^{161} + \ _{0}n^{1}$
