The correct answer uses 'LATERAL FLATTEN' to unnest the 'attributes' array, and then uses
'LISTAGG' to concatenate the 'name' values into a comma-separated string. The 'WITHIN GROUP (ORDER BY seq)' clause ensures a consistent order. Option B is incorrect because it's trying to filter by key after flattening the 'attributes' array, which isn't how 'LATERAL FLATTEN' works. The correct column name 'name' needed to be referenced directly after the flatten command. Option A is syntactically incorrect for JSON array access. XMLAGG is not used for JSON. Option E incorrect because 'name' is a column after flatten is perfomed.
