Answer
Answer: A ✓ checked by 4AB · confidence high
Answer: a–IV, b–I, c–III, d–II.
Explanation
Answer: a–IV, b–I, c–III, d–II — Magic numbers come from the nuclear shell model. The liquid-drop model explains fission. Actinides are all radioactive. Threshold energy is fixed by the Q-value of an endoergic reaction.
