All right. Hi, everyone. So this question is asking us which element among group six A elements is the most abundant in the human body. Option A says oxygen, option B is sulfur. Option C is selenium and option D is polonium. So for questions like these, it could be more productive to first eliminate what cannot be true because of the answer. Choices listed here, recall that polonium is actually radioactive, meaning that it along with tellurium is actually toxic to humans, right? So it makes sense that polonium and tellurium for that matter would not be abundant in the human body. And matter of fact, it would make sense that they're not going to be present at all. Right. So I can go ahead and cross out polonium because it would not make sense for polonium to be present in the human body considering its toxicity. Now, recall also that the majority of the human body is composed of water at approximately 60% right. So 60% of your body is composed of water, which is composed of hydrogen and oxygen. So from this information alone, we can tell that oxygen is going to be the most abundant element of all the ones listed in group six A or from group six A. So our choice is going to be option A because oxygen is what partially composes water, which is the substance that's most abundant in the human body. Right now, sulfur, sulfur accounts for really less than 1% of the total human body at about 0.20%. So, not abundant at all. Right. And the same can be said for selenium because the total abundance of selenium is even less than that of sulfur. So with that being said, our only answer choice is going to be option A which is oxygen. So with that being said, thank you very much for watching and I hope you found this helpful.
