In a FLATTEN function call, what does the MODE parameter specify?

Whether to include rows for empty arrays and objects.

The data type of the column that contains the semi-structured data.

Whether to flatten arrays, objects, or both.

The maximum depth of recursion for nested structures.

When using the FLATTEN function in Snowflake, what does the THIS parameter control?

The maximum depth of nesting to flatten

The mode that determines whether to include outer rows

The input expression that contains the semi-structured data to be flattened

The output column name for the flattened data

Which statement correctly describes the relationship between the VALUE and THIS parameters in a FLATTEN operation?

VALUE is the output column that contains each element extracted from the input expression specified by THIS.

VALUE is used only when THIS is an array, and THIS is used only when the input is an object.

VALUE and THIS are interchangeable aliases for the same column.

VALUE is the input expression, and THIS is the output column containing the flattened data.
