Explanation:
Amazon CloudWatch Logs Insights allows you to interactively search and analyze your log data. You can query multiple log groups simultaneously (up to 50). Using the 'stats' command with the 'count()' function and a 'by' clause allows you to aggregate and count specific events (like errors) grouped by a specific field (like error type). Option B is incorrect because standard log search doesn't support 'groupby' syntax. Option C is possible but requires exporting logs to S3 first, which adds complexity. Option D is irrelevant as the data is in CloudWatch, not an RDS database.
