The Jscrambler configuration file, typically named jscrambler.json or .jscramblerrc, uses the JSON (JavaScript Object Notation) format. This file contains key-value pairs that define the protection settings, such as which transformations to apply, application-specific keys, and file inclusion/exclusion patterns. The scenario describes Helena removing sensitive keys from this file, which is a standard practice when using environment variables for secrets in a CI/CD pipeline, a common pattern for JSON configuration files.

B. XML is a valid data-interchange format but is not the format used for the Jscrambler configuration file.

C. YAML is commonly used for CI/CD pipeline definitions (like in GitLab) but is not the native format for the .jscramblerrc file.

D. HTML is a markup language for creating web pages and is not used for application configuration files.
