The correct answer to this question is B, Thin, moist alveolus walls, covered by a network of blood capillaries. This type of question would be found on a science test for an early learner, such as an elementary school student. It could also be found on an IQ test to test one's intelligence.

Alveoli are the machine that helps with breathing. It is essential to breathe and can break down at any time, due to things like disease or smoking. Blood Capillaries are also crucial because they are where the transfer of oxygen takes place. They are also the site of where carbon dioxide waste is collected.
