Correct option is C

Conclusion I: Some nights are buses.

• From statement 4, all days are nights, and from statement 3, some cars are days. However, there is no direct relationship connecting buses to nights via these statements.
• Conclusion I does not follow.

Conclusion II: Some nights are cars.

• Conclusion II follows.

Conclusion III: Some days are buses.
