Option 1 : Neither conclusion I nor II follows.

The least possible Venn diagram for the given statement is as below:

I) All chairs are boards → Does not follow → As all windows are board and some chairs are windows. So all chairs are boards it can be possible but not definite.

II) All boards are windows → Does not follow → As all windows are boards, So all boards cannot be windows.

Hence, the correct answer is  "Neither conclusion I nor II follows".
