Explanation

Option A (lifecycle policy transitioning to S3 Standard-IA after 30 days) is the most cost-effective solution that meets the exact requirements. Records start in S3 Standard (immediate, frequent access for 30 days) and automatically transition to S3 Standard-IA (lower storage cost for infrequent access after 30 days). Option B (S3 Intelligent-Tiering) adds a per-object monitoring and automation fee; since the access pattern is predictable (frequent for 30 days, infrequent after), a lifecycle policy is cheaper. Option C (S3 Glacier Deep Archive) is for archival - retrieval takes hours and doesn't meet the 'infrequent access' requirement. Option D (S3 Standard-IA for all records) incurs retrieval fees and has a 30-day minimum storage charge, making it suboptimal for the first 30 days of frequent access.
