Who cannot be a member of a team of six members?

If Rawat is selected, Shalini cannot be selected. Also, Shalini and Kapil will be selected together. Therefore, if Shalini is not selected, Kapil will also not be selected.
It is mentioned that exactly one from Prateek or Tarun will be selected. Taking all the conditions into consideration, Rawat cannot be a member of a team having six members.
