Final answer:
In computer science, you can never change the Rx from CII to VI, which refers to the usage of prescribed medication. The Roman numerals CII and VI represent different levels of controlled substances.
Step-by-step explanation:
In computer science, you can NEVER change the **Rx** from CII to VI. The **Rx** refers to the **usage of prescribed medication**. The Roman numerals **CII** and **VI** represent different levels of controlled substances, where **CII** indicates a high potential for abuse and **VI** indicates the lowest potential for abuse. Therefore, it is crucial to follow the appropriate regulations and restrictions when it comes to medication and its classifications.
