Let’s end this :D
In the question
- Conclusion I:Conclusion I: Some pathogens are bacteria.
- Conclusion II:Conclusion II: All pathogens are not bacteria
There can be two possible cases
Consider Case 1
Where bacteria and pathogen are both subsets of microorganisms &
Bacteria ∩ Pathogen = null
For this case
Conclusion I fails but conclusion II passes
So we rule out Option A & D
Consider Case 2
Where bacteria and pathogen are both subsets of microorganisms &
Bacteria ∩ Pathogen = not null
For this case
Conclusion I passes but conclusion II fails
So we rule out Option B now
Now the question doesn’t say if its OR or XOR
and only conclusive logic we can derive is XOR
So C satisfies either one of the conditions at a time
It can never satisfy both or none cause its like
Schrödinger's cat experiment
The cat can either be alive or dead
It cannot be both dead or alive
Nor it cannot be both not dead not alive
So Final ANSWER C :D
Please fell free to try to correct a question which you definitely messed up. :D
