• A. ${}_{4}^{9}Be +_{2}^{4}He \rightarrow_{6}^{12}C +_{0}^{- 1}n$
• B. ${}_{2}^{3}He +_{2}^{3}He \rightarrow_{2}^{4}He +_{1}^{1}H +_{1}^{1}H$
• C. ${}_{56}^{144}Ba +_{56}^{92}Kr \rightarrow_{92}^{235}U +_{0}^{- 1}n$
• D. ${}_{26}^{56}Fe +_{48}^{112}Ca \rightarrow_{74}^{167}W +_{0}^{- 1}n$

Answer 1

Answer: (B)

${}_{2}^{3}He +_{2}^{3}He \rightarrow_{2}^{4}He +_{1}^{1}H +_{1}^{1}H$

Answer 2

Energy is released in the sun due to fusion.
