Answer:
It increases haemoglobin's affinity.
Explanation:
When CO binds to one heme molecule, the haemoglobin molecule becomes in a relaxed state and oxygen can bind so very easily.
The problem is not in the uptake of oxygen, it's with its delivery. The affinity for oxygen increases so much such that it becomes impossible to release and deliver the oxygen to tissues.
Neither of these are minerals, B.
Its not A because, they are not natural materials but instead made up of natural materials, like a rubber tree.
Its not C because, like I said, plastic is made from rubber trees, this garentees it doesnt have a crystal structure.
Its not D because, concrete is not a mineral and has indefinite composition.
Shrubs is the best answer ;)
