Two statements are given followed by conclusions. Assuming the statements to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow (s) from the statements.
Statements:

I. Some elephants are chairs.

II. All elephants are doors.
Conclusions:

II. All doors are elephants. ​​
