You have an application running on Google Kubernetes Engine (GKE). The application is currently using a logging library and is outputting to standard output. You need to export the logs to Cloud Logging, and you need the logs to include metadata about each request. You want to use the simplest method to accomplish this. What should you do?

A. Change your application’s logging library to the Cloud Logging library, and configure your application to export logs to Cloud Logging. B. Update your application to output logs in JSON format, and add the necessary metadata to the JSON. C. Update your application to output logs in CSV format, and add the necessary metadata to the CSV. D. Install the Fluent Bit agent on each of your GKE nodes, and have the agent export all logs from /var/log.
