Answer
This statement is false. Alpha decay does not provide evidence for neutrinos; rather, the existence of neutrinos was inferred from beta decay processes. Alpha decay involves the emission of alpha particles which do not involve neutrinos.
Step 3
III. The W-boson is associated with the strong nuclear force.

Answer
This statement is also false. The W-boson is actually associated with the weak nuclear force, not the strong nuclear force. The strong nuclear force is mediated by gluons.
