Explanation

Cloud Bigtable is designed for high-throughput, low-latency workloads such as ecommerce with real-time data access requirements. Bigtable natively supports garbage collection policies at the column family level, which automatically delete data based on age (e.g., cells older than 30 days) - this is the built-in, most efficient mechanism for time-based deletion. Option C is incorrect because Bigtable uses 'garbage collection policies,' not generic 'TTL policies' - the terminology matters on the exam and reflects the actual feature. Options A and B use Spanner, which is better suited for relational, transactional workloads; additionally, Data Catalog (A) is a metadata service that does not delete data.
