in the topic take test of chemistry topic-3 oxygeb-carbondioxide cycle in q.3 it is not mentioned that we have to choose the incorrect or correct option so if we are choosing the option a at last they are showing we have one mistake that the correct answer is option d but according to us option a is also correct so please give the question properly.

 I have checked the concerned question. There is no such problem. Please carefully go through the question again.
