The best and most correct answer among the choices provided by your question is the first choice which is "An unstable nucleus decays into a more stable nucleus."
Radioactive decay (also known as nuclear decay or radioactivity) is the process by which the nucleus of an unstable atom loses energy by emitting radiation, including alpha particles, beta particles, gamma rays, and conversion electrons. A material that spontaneously emits such radiation is considered radioactive.

The statement that correctly describes the process of radioactive decay is as follows: an unstable nucleus decays into a more stable nucleus.
What is radioactive decay?
Radioactive decay refers to any of several processes by which unstable nuclei emit subatomic particles and/or ionizing radiation and disintegrate into one or more smaller nuclei.
Radioactive decays usually involve the breakdown of an unstable nuclei into a more stable one.
According to this question, Americium-241 decays into neptunium-237. This suggests that an unstable nucleus decays into a more stable nucleus.
