Final answer:
The conclusion that follows from the given statements with absolute certainty is that c. no stamp collectors are drones.
Step-by-step explanation:
The drones are all collectors of stamps. In this case, it is safe to say that stamp collectors and architects are two distinct groups with no overlap; that is, not one stamp collector is an architect. Consequently, the first sentence suggests: Stamp collectors... architects In a similar vein, it can be said with certainty that all drones are members of the stamp-collecting community.
Thus, the conclusion that follows from the given statements with absolute certainty is that no stamp collectors are drones. Given that all the drones are stamp collectors, and none of the stamp collectors are architects, it is clear that there is no overlap between stamp collectors and drones. Therefore, the conclusion is that no stamp collectors are drones.
