D. It is much greater.

Reason: nuclear decays release MeV (10^6 eV) of energy per nucleus whereas chemical reactions release eV (1–10 eV) per atom or bond. Converting to energy per gram gives nuclear processes about 10^5–10^7 times more energy per gram than typical chemical reactions (e.g., combustion ≈ 10^4–10^5 J/g vs nuclear ≈ 10^9–10^11 J/g).
