THAT DOESN'T MAKE SENSE. the diagram has no relation to the questions or the options because the figure of the concentration of oxygen in blood of something but the options and the questions are related to plants. the labels in the diagram are P,Q,R,S meanwhile the labels in the questions areX,Y,Z. There are a lot of errors like this that I am facing nowadays so I would kindly request S O F to please correct these issues ,specially in chapterwise
