You are deploying your application to a Compute Engine virtual machine instance. Your application is configured to write its log files to disk. You want to view the logs in Stackdriver Logging without changing the application code.
What should you do?

A. Install the Stackdriver Logging Agent and configure it to send the application logs. B. Use a Stackdriver Logging Library to log directly from the application to Stackdriver Logging. C. Provide the log file folder path in the metadata of the instance to configure it to send the application logs. D. Change the application to log to /var/log so that its logs are automatically sent to Stackdriver Logging.
