Explanation

Amazon S3 Standard provides highly durable, scalable storage with no retrieval delays. For short-lived data that persists only 24 hours, S3 Standard is the most cost-effective because storage classes with lower costs (like Glacier or S3 One Zone-IA) are designed for long-term or infrequently accessed data, and using them would incur unnecessary retrieval or lifecycle costs for such short-lived logs.
