The correct answers are B. In a CREATE STAGE statement and E. In a COPY INTO < location > statement .
When unloading data from Snowflake, file format options can be specified directly in the COPY INTO < location > command or associated with a named stage. Defining the file format in a stage is useful when repeated loads or unloads use the same format settings.
Why B is correct:
A stage can include a file format definition or reference. When data is unloaded to that stage, the file format associated with the stage can be used.
Example:
CREATE STAGE my_stage
FILE_FORMAT = (TYPE = CSV FIELD_DELIMITER = ' , ' );
COPY INTO @my_stage
FROM my_table;
Why E is correct:
The COPY INTO < location > command can specify file format options directly.
Example:
COPY INTO @my_stage/output/
FROM my_table
FILE_FORMAT = (TYPE = CSV COMPRESSION = GZIP);
Why the other options are incorrect:
A). A SELECT statement defines the query result to unload, but file format options are not specified as part of a normal SELECT.
C). A database definition does not define unload file format options.
D). An integration defines access to external services or storage, not the file format used for unloading.

Snowflake documentation explains that file format options can be specified in the COPY INTO < location > command or as part of a named stage definition.
