Selected Answer: A
To load files whose metadata has expired, set the LOAD_UNCERTAIN_FILES copy option to true. The copy option references load metadata, if available, to avoid data duplication, but also attempts to load files with expired load metadata.

To load files whose metadata has expired, set the LOAD_UNCERTAIN_FILES copy option to true. The copy option references load metadata, if available, to avoid data duplication, but also attempts to load files with expired load metadata. Alternatively, set the FORCE option to load all files, ignoring load metadata if it exists. Note that this option reloads files, potentially duplicating data in a table.

B correct - Boolean that specifies to load all files, regardless of whether they’ve been loaded previously and have not changed since they were loaded. Note that this option reloads files, potentially duplicating data in a table. https://docs.snowflake.com/en/sql-reference/sql/copy-into-table
