What kind of operations can the pytz module perform?

The pytz module is specifically designed for date and time manipulation in Python. It allows developers to work with time zones, providing accurate conversions and calculations related to both local and UTC times. By utilizing pytz, you can easily convert datetime objects between different time zones, handle daylight saving time transitions, and ensure that time-related data is accurately represented for various global locations. This functionality is essential for applications that require precise timing across different geographical areas, such as scheduling, logging events, or managing deadlines.

The other options do not pertain to the core capabilities of the pytz module. Data visualization involves creating graphical representations of data, which is handled by libraries like Matplotlib or Seaborn. String manipulation deals with modifying and processing strings of text, typically using Python's built-in string methods. JSON parsing refers to working with data in the JSON format, usually accomplished with the built-in json module in Python. In summary, pytz's primary focus is on date and time manipulation, which makes this the correct and relevant choice.
