In a Snowflake SQL query, what does the THIS parameter of the FLATTEN function refer to?

The name of the column that contains the nested data to be flattened.

A reference to the current element being processed within the flattened output.

The path expression that specifies which nested level to flatten.

The alias assigned to the output of the FLATTEN function.

In a Snowflake SQL query, what is the purpose of the MODE parameter in the FLATTEN function?

It determines whether to output only object keys, only array values, or both.

It sets the maximum number of rows returned by the FLATTEN operation.

It specifies whether to recurse into nested arrays and objects.

It controls the depth of flattening for multi-level semi-structured data.
