What is the penalty for possession of substance penalty group 1-A if the quantity is more than 8,000?

The correct answer is based on the classification of offenses related to controlled substances, specifically those in penalty group 1-A. When the quantity of a substance in this classification is more than 8,000 grams, it is considered a serious felony offense. The law provides for severe penalties to deter large-scale trafficking and possession of highly dangerous drugs.

In this case, the penalty is classified as a first-degree felony, which carries a punishment of life imprisonment or a term ranging from 15 years to 99 years. This reflects the state's approach to handling offenses that involve a significant quantity of controlled substances. By establishing such a stringent penalty, the legal system aims to combat drug-related crime effectively.

Looking at the other options, they represent lesser degrees of felonies or penalties that do not align with the severity of charges associated with such a large amount of substance in penalty group 1-A. As a result, they do not apply in this case where the quantity exceeds 8,000 grams.
