Answer:
The correct answer is "carbon-14 and hydrogen-3 would most likely decay because their neutrons and protons are not equal".
Step-by-step explanation:
Nuclear decay, also known as radioactive decay, is a process at which an atom losses energy gradually in the form of radiation. This process occurs particularly in atoms with an unstable nucleus, which happens when the numbers of protons and neutrons are not equal. In this case, carbon-14 and hydrogen-3 would most likely decay because they have this characteristic. The difference between protons and neutrons is known as neutron-proton ratio, and the larger it is the most unstable the nucleus is.
