C)  if either conclusion I or II follows.

D)  if neither conclusion I nor II follows.

E)  if both conclusions I and II follow.

Correct Answer: E

Solution :

 No train is a truck  conversion  No truck is a train  + Some trains are tumblers (I) = E +1 = O* = Some tumblers are not trucks it means All trucks being tumblers is a possibility. Hence, conclusion I follows. Again, No train is a truck  + All trucks are toys  = E + A = O* = Some toys are not trains. Thus conclusion II follows.
