The correct answers are A and C. According to Snowflake's official documentation and the community consensus (with AC receiving 91% support), storage costs in Snowflake are determined by account type (On-Demand vs Capacity) and the cloud region (US, EU, APAC, etc.). The account type affects pricing tiers, while different regions have varying infrastructure costs that influence the flat per-TB rate. Options B (storage file format) and D (type of data) do not impact costs as Snowflake handles compression and optimization internally. Option E (cloud platform) is incorrect because Snowflake abstracts cloud provider differences into their published regional pricing, so customers pay Snowflake's rates regardless of the underlying AWS, Azure, or Google Cloud platform.
