A question about the law of Romanian Repatriation program

If the mother applied to the repatriation citizenship program based on her ancestor and finally she got the citizenship, whether Child (More then 21 years old) can apply the citizenship based on her? I saw the articles it says that mother's ancestor(There is a generation limitation maybe) must be a citizen or lost the citizenship between a fix time period in history，if in this case, whether child can apply the citizenship(Not residence permit) based on his mother's citizenship, not based on his mother's ancestor's citizenship? I think there is a difference for applying by repatriation and applying by descent? The mother can apply citizenship based on ancestor A according to the repatriation program, but for child, he can apply based on mother, if based on A, the generation limit requirement will not be passed. Is there correct? Or Child can only apply PR not citizenship?
