What is the recommended file sizing for data loading using Snowpipe?
The recommended file size for data loading using Snowpipe is typically within the range of 100 MB to 250 MB. This size range helps to reduce the overhead charge relative to the amount of total data loaded, ensuring a balance between performance and cost efficiency. Files smaller than 100 MB may incur higher overhead per megabyte of data processed, and larger files up to 250 MB are managed effectively by Snowpipe.
Loading data files roughly 100-250 MB in size or larger reduces the overhead charge relative to the amount of total data loaded to the point where the overhead cost is immaterial.

There is a fixed, per-file overhead charge for Snowpipe in addition to the compute processing costs. We recommend files at least above 10 MB on average, with files in the 100 to 250 MB range offering the best cost-to-performance ratio. https://www.snowflake.com/blog/best-practices-for-data-ingestion/#:~:text=Recommended%20file%20size%20for%20Snowpipe%20and%20cost%20considerations&text=We%20recommend%20files%20at%20least,cost%2Dto%2Dperformance%20ratio.

C. When the underlying data has changed
i think A is the answer
correct
A is correct
I suspect these "best practices" where updated with time. I have documentation dated June 2020 from attending a Snowflake Quickstart Training (by Snowflake Proffessional Services) that aligns with the moderated answer.
