Answer: Per-second/per-core granularity

The correct answer is B based on Snowflake's official documentation and the community consensus. Snowpipe charges are calculated with per-second/per-core granularity, as Snowpipe uses serverless compute that tracks resource consumption at this detailed level. This granular billing approach allows for precise charging based on actual CPU usage during data loading operations. Option A is incorrect because Snowpipe doesn't use traditional warehouses with fixed sizes. Option C is wrong as billing isn't based on the number of pipes. Option D is incorrect because storage costs are separate from Snowpipe compute charges.
