​Conclusion​

I: "All windows are walls" can be inferred because: All windows are doors, and all doors are walls. Hence, all windows are also walls. Conclusion I is true.

II: "Some doors are windows" can be inferred because: All windows are doors, which implies there is an overlap between doors and windows. Hence, some doors are windows. Conclusion II is true.

Correct answer is both Conclusion I and II follow.
