D. fusion reaction
Explanation: Endothermic reactions absorb energy. Exothermic (chemical) reactions release far less energy per gram (typically 10^4–10^5 J/g) than nuclear reactions. Fission releases ~8×10^10 J/g (U-235), while fusion (e.g., H → He) releases even more (~6×10^11 J/g). Therefore fusion gives the greatest energy per gram.
