Which of the following is NOT a method for exporting a packet capture?

In the context of exporting packet captures, the correct answer is based on the common formats used in packet analysis. PCapNG is a well-known format specifically designed for network packet captures, allowing for detailed information storage. HTML can be utilized to present captured data in a web browser, while Text format allows the export of raw data in a readable form.

However, JSON, while a widely used format in data interchange, is not typically associated with exporting packet captures from network analysis tools. It is primarily designed for structuring data in a way that is easy for machines to parse and generate, especially in web applications. Thus, it is not a standard export format for packet captures, making it the correct response to the question.
