Explanation

YAML supports comments using the '#' character, while the JSON specification explicitly does not support comments. This is a key syntactic difference between the two formats. Option B is incorrect because JSON uses both curly brackets '{}' for objects and square brackets '[]' for arrays, and YAML uses indentation-based structure rather than only square brackets. Option C is incorrect because both YAML and JSON are used broadly across web development, DevOps, configuration management, and APIs - neither is restricted to back-end systems only. Option D is incorrect because YAML is actively maintained and widely used (e.g., in Kubernetes, Docker Compose, and CI/CD pipelines); it has not been deprecated.
