Final answer:
Data modification is not a primary business charting objective; it is a pre-processing step for data management, while data exploration, argumentation, and hypothesis testing are actual charting objectives.
Step-by-step explanation:
The option that is NOT a primary business charting objective is Data modification. The primary objectives of business charting usually encompass Data exploration, which involves investigating the data to find patterns or insights; Argumentation, which refers to using charts to support a specific point or argument; and Hypothesis testing, which is about validating or refuting a hypothesis using visual representations of data. Data modification, on the other hand, is not a charting objective but rather a data management activity that involves changing data to correct errors or adjust its format, which normally occurs before the charting process.
