The correct answer is: B. non-poisonous

The colors are added to the alcohol to make it blue, so that it can be easily identified. This alcohol is called non-poisonous alcohol. It is a type of alcohol that is not poisonous and can be consumed by humans. It is often used in food and beverages, as well as in some industrial applications.

The other options are incorrect because:

• A. mature alcohol is not a common term. It is possible that the question is referring to aged alcohol, which is alcohol that has been stored for a long period of time. Aged alcohol can be more expensive than non-aged alcohol, and it is sometimes believed to have a better flavor.
• C. poisonous (deformed) alcohol is not a common term. It is possible that the question is referring to denatured alcohol, which is alcohol that has been made poisonous by adding other chemicals. Denatured alcohol is not meant to be consumed by humans, and it is often used as a solvent or fuel.
• D. natural alcohol is not a common term. It is possible that the question is referring to ethanol, which is the type of alcohol that is found in alcoholic beverages. Ethanol is a natural product that is produced by fermentation.
