The correct answer is Streaming telemetry from distributed edge sensors in manufacturing plants.

Streaming telemetry from distributed edge sensors in manufacturing plants represents a continuous flow of small, frequent events that must be processed as they arrive for real time monitoring, alerting, and anomaly detection. Streaming systems are designed for low latency and continual ingestion, which matches the characteristics of telemetry from distributed sensors.

Transferring sales records that are older than 45 days to an offsite archive is an archival activity that is infrequent and tolerant of latency, so it is a batch workload rather than streaming.

Batch uploading point of sale transaction files once every 24 hours explicitly describes periodic bulk uploads and therefore fits batch processing, not continuous streaming.

Exporting cloud operations metadata every 90 minutes for periodic analysis is a scheduled, periodic export and is closer to a scheduled batch or micro batch workflow rather than a true continuous streaming workload.
