B Correct answer
Explanation

Humans cannot breathe in space because there is no atmosphere - space is a vacuum with essentially zero pressure and no oxygen. Without a pressurized spacesuit supplying oxygen, humans would lose consciousness within 15 seconds and die within minutes. The vacuum of space would also cause bodily fluids to boil. Therefore, the statement is false.
