Answer 2

Answer:

I find option (2) to be correct.

Explanation:

Dead space air is the air which is taken in the lungs, but does not participate in gaseous exchange. The air in the bronchi tree that does not reach the alveoli does not get to involve in gaseous exchange.

An incredible question asked, by the way. Loved it.
