From the given list, let's determine the element which is created by radioactive decay and nuclear reactions in the sun.
The radioactive decay and nuclear reactions in the sun can be said to be a fusion process in the sun.
The Neutrinos are created during the process of Nuclear fusion in the sun.
Electrons, Protons, and Neutrons are the sub-atomic particles which make up an atom. These three elements are not created during the fusion process in the sun.
Therefore, the neutrinos are created by radioactive decay and nuclear reactions in the sun.
• ANSWER:
D. Neutrinos
