The correct answer is: Yeast.
Yeast is a single-celled fungus that is used to make bread, beer, and wine. It is also used to produce industrial products such as ethanol, butanol, and lactic acid. Yeast is a versatile organism that can be grown in a variety of environments, making it a cost-effective and efficient way to produce these products.
Viruses are not living organisms and cannot be used to manufacture products. Bacteria are living organisms, but they are not as efficient as yeast at producing industrial products. Fungi are living organisms that can be used to manufacture some industrial products, but they are not as versatile as yeast.
Acetic acid, acetone, butanol, lactic acid, and several vitamins are all products that can be manufactured by yeast. Acetic acid is used in the production of vinegar, acetone is used in the production of nail polish remover, butanol is used as a fuel, lactic acid is used in the production of cheese, and vitamins are essential for human health.
Yeast is a valuable organism that has many applications in industry and agriculture. It is a versatile, efficient, and cost-effective way to produce a variety of products.
