Correct Answer: Rawat
Explanation:
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.
Correct Answer: Six
Explanation:
If Shalini is selected, Rawat is definitely not selected. Also, exactly one from Prateek or Tarun is selected, that is, the team can have a maximum of six members.
