Which statement about biological and non-biological substances is correct?

The assertion that both statements are correct and that the human body consists only of biological substances is inaccurate, leading to the conclusion that the first statement requires reevaluation. Biological substances are indeed those derived from living organisms and typically need oxygen for processes such as respiration, but the human body also contains non-biological substances, such as water and minerals, which play essential roles in bodily functions.

The option that claims biological substances do not require oxygen is misleading, as many biological processes depend on oxygen. Therefore, the choice that concludes one statement is correct while acknowledging the inaccuracy of the other reflects a clearer understanding of the nature of biological and non-biological substances, confirming that the relationship between these categories is more nuanced than simply one being the entirety of the other.
