Answer 1

To be classified as a vitamin, a substance needs to produce deficiency symptoms over time, cannot be synthesized by the body, and is composed of non-carbon-containing substances.

Step-by-step explanation:

To be classified as a vitamin, a substance should meet the following criteria:

• Over time, a lack produces deficiency symptoms. Vitamins are essential for the body's normal functioning, and a deficiency can lead to various health problems.
• The body is unable to synthesize enough to maintain health. Unlike other nutrients, vitamins cannot be produced in sufficient amounts by the body, so they need to be obtained through diet.
• They are composed of non-carbon-containing substances. Vitamins are organic compounds, which means they contain carbon.

Therefore, the correct criteria for a substance to be classified as a vitamin are that it must produce deficiency symptoms over time, the body cannot synthesize enough of it, and it is composed of non-carbon-containing substances.
