At least two people must accept their invites
(A) Both Adam and Kate do not go
NOT TRUE. 4th condition says at least one of them does not go. So there may be cases when one of them goes to interview
(B) Sam goes if Adam goes
TRUE. If Adam goes Kate doesn't go. Kate does not go only if Sam goes. So Sam goes.
(C) Barbara goes if Sam goes
NOT TRUE. If Sam goes Kate doesn't. When Kate doesn't go Adam may or may not go. Hence Barbara may or may not go.
(D) At least one of Barbara and Cohen go
NOT TRUE. At least two must go to interview. If Sam and Adam goes to interview, Kate doesn't go and because of that Cohen does not go. When Adam is going Barbara may or may not go. So it is not true always.

Sam going is necessary for Kate not going.
If Sam does not go, Kate must go.
At least one of Adam and Kate do not go.
If Kate is going, Adam cannot go. Then Barbara goes too.
Also as per this condition then,
If Adam goes, then Kate cannot go. Then Sam must go (necessary).
Hence, we get if Adam goes, then Sam must go too.
Answer (B)
