D. Species of family members

The question is only for the first day of course (when it does not fall on Shabbat. Not this year), since on the other days the species do not need to be the taker’s. I think in such a case there is no problem because in the process of selection it becomes clear who each set belongs to. When I took the particular set I took, it was determined that it was my set. Although in the Torah there is no choice, in partnership there is (see Gemara R. Sh. Sh. Sh. Ben-Naidrim), and in particular here that the result must only exist from now on (it is not important that it be mine at the beginning of the day, but only when I take it. This was emphasized in the Rashba’s response, in which the 23rd century did not disagree that there is a choice). Although one can wonder whether there is jealousy here on the day of the Torah, but according to the law there is no problem because the jealousy was made by the Ba’u’i and only the clarification is being made now.
