Vitamins are inorganic compounds used by the body for metabolism.
a. true
b. false

The correct answer is A. False

Explanation:

Vitamins are organic compounds or molecules rather than inorganic ones which means they are mainly composed of carbon and they are related to living organism different from minerals that come from non-living elements such as water or earth. Vitamins are essential for the metabolism in an organism including functions such as growth due to this, they are necessary but in most cases only in small quantities. Additionally, vitamins are obtained through diet or similar rather than synthesize by the organism. According to this, it is false "Vitamins are inorganic compounds used by the body for metabolism" because even though they are necessary for the metabolism, vitamins are organic and not inorganic compounds.
