Answer:
All of the choices are correct.
Explanation:
The most notable one is that it "kept them calm".
It was much more than that. People being removed from their homes, family, and anything they knew had nothing left. Allowing luggage let them keep a sense of connection to their old, own world. Their trains were being disguised as [something along the lines of] "Labour Deployment” or “Resettlement in the East", and bringing luggage helped that disguise appear as possible.
By being allowed to bring luggage, there was also a promise that there would be life at their destination, and that there was no need to try to escape now because the future would hold "hope".

Being stripped of luggage and personal belongings also contributed to the inferiority of Jewish people/people in concentration camps.
People would bring items of high personal value, such as their wedding dress. This would greatly lower their morale, as expressed in that answer choice.
