since jasmine becomes unhappy is samir is there so these 2 can not be invited together
1) jasmine and kanti (both r happy) possible
2)jasmine and samir not possible
3)kanti and samir not possible (as jasmine is not there which is a prerequisite for kanti)
4)all three not possible as jasmine will be unhappy with samir
5) jasmine alone is possible as there is not condition violation for jasmine
6)only samir or kanti not possible
so only no 1) and no 5) r possible
