Why is this query unsuitable for assembling a rule-based audience of those who have completed a conversion event? SELECT user_id FROM conversions

• The query requires a WHERE clause to specify the relevant conversion event type(s)
• The query cannot include user_id as a dimension within the final SELECT statement
• The query does not leverage an audience-specific table
• The query requires a GROUP BY statement

The correct answer is:

• The query does not leverage an audience-specific table
