Explanation

Option B (False) is correct because the statement oversimplifies what Prometheus does. Prometheus is not merely a data collection tool - it also stores metrics in its own built-in time-series database (TSDB) and provides PromQL, a powerful query language used for data processing, aggregation, and alerting logic. The claim that Prometheus "mainly" handles data collection while Grafana handles display misses that Prometheus itself is responsible for scraping, storing, and querying metrics, with Grafana serving as the visualization layer on top.

Option A (True) is wrong because it accepts the flawed characterization that Prometheus is limited to collection and that the two tools have a clean separation of responsibilities; in reality, Prometheus handles significant processing duties independently of Grafana.

Memory tip: Think of Prometheus as a full pipeline on its own - it scrapes, stores, and queries data - while Grafana is the front-end display layer that reads from Prometheus (or other data sources). Prometheus can operate and alert without Grafana at all, which proves it does far more than just collect data.
