Explanation

The given statement is "All Windows Are Doors, No Door Is Wall".

Conclusion (I) "No Windows Is Wall" follows from the given statement because all windows are doors and no door is a wall, therefore, no windows can be a wall.

Conclusion (II) "No Wall Is Door" also follows from the given statement because if no door is a wall, then it means that a wall cannot be a door.

Therefore, both conclusions (I) and (II) follow from the given statement.

Hence, the correct answer is (D) both conclusion (I) and (II) follow.
