What changes in data processing when a gas utility checks the condition of its assets...

Switching from human inspection to drones changes the data from direct condition reports to raw observation data (e.g., images or sensor readings) that requires analysis to derive asset conditions. The DAMA-DMBOK notes: “The introduction of new data collection methods, such as IoT or drones, often shifts data processing from structured, interpreted data to raw, observational data that requires additional processing to extract meaningful insights” (DMBOK2, Chapter 13: Data Integration and Interoperability, p. 517).

Options B, D, and E misalign data types (e.g., reference, master, or metadata are not relevant here), and C is incorrect as video data is typically harder to process than structured data.
