Show answer & explanation

Answer: (B) Neither Conclusion I nor II follows.

Explanation

From 'Some kings are queens' and 'All queens are beautiful' we can only say that some kings are beautiful. 'All kings are beautiful' does not follow, and 'All queens are kings' cannot be drawn from 'some kings are queens'. So neither conclusion follows.
