To delete a topic in Kafka, the appropriate mechanism is to use the Kafka command-line tool with the `--delete` option. This command allows users to remove a topic from the Kafka cluster by specifying the topic name. When executed, the broker will process the deletion request and remove all associated data and metadata related to that specific topic.

The `--delete` option is specifically designed for this purpose and integrates with Kafka’s internals to ensure that the topic is completely cleaned up from the system. This is a straightforward, efficient way to manage topics in Kafka, allowing for easy administration of the Kafka environment.

Other options such as modifying the configuration file or stopping the Kafka broker are not valid methods for topic deletion. Configuration adjustments might affect topic settings or broker behavior, but they do not facilitate topic deletion directly. Likewise, stopping the broker halts all operations but does not inherently delete any topics. The command that involves `--remove` does not exist in the Kafka command suite and does not provide the capability to delete topics.
