Solution

The correct option is A Parent nucleus
A reaction is spontaneous only when the products (daughter nuclei) have lesser energy state than the reactants (parent nucleus). So, the same is the case with alpha decay, which is a spontaneous process. Therefore, the parent nucleus has higher energy than its daughters.
