ONLiNE UPSC · Accepted Answer

Let&rsquo;s restate the logic:
Some developers are trainers
All trainers &rarr; project managers
All project managers &rarr; team leaders
⟹ So, some developers are trainers ⟶ project managers ⟶ team leaders
Therefore:
Conclusion I: Some team leaders are software developers (True)
Conclusion II: All project managers are software developers (False)
Conclusion III: Some project managers are software developers (True)
Hence, option c is correct.
