Answer 4

@shear1945 I would say D (also, @alphadxg you said C, respiratory but C is circulatory). D is certainly 100% directly affected, but you cannot really separate the respiratory and circulatory systems. No lungs, the blood cannot get oxygen and without blood our lungs are worthless. So, it might be C and D, even though I think the circulatory bit is not quite a direct thing.

@alphadxg Why A? That is the system that deals with hormones and the like. How would it be directly affected? In the end everything is affected due to lack of oxygen, but I cannot see A being an answer.
