Selected Answer: C

The most efficient way to identify the relevant data is to leverage business domain knowledge about which units are responsible for the chemical operations rather than trying to discover that from raw data alone. Thus: C. Consult with the business team to identify which sites are responsible for chemical operations and ingest only the relevant data for analysis.
