Neither conclusion I nor conclusion II follows
E
Both conclusions I and conclusion II follow

Solution

The correct option is D Only conclusion II follows All stars are bottles → conversion → some bottles are stars. Hence, conclusion II follows. All stars are bottles + some bottles are papers + No paper is calendar =  A + I + E = A + (I + E) = A + O = No conclusion. Therefore, "All calendars being stars is a possiblity" does not exist. Therefore, only conclusion II follows.
