If a database system's query optimizer relies solely on set theory's laws for simplification, which outcome occurs when evaluating a complex query with multiple joins and intersections?

💡 Explanation

The query optimizer uses set theory's algebraic properties to rewrite complex queries into simpler, logically equivalent forms, because this simplification reduces computational complexity. Therefore, a logically equivalent query rewrite will occur, rather than guaranteeing an optimal execution plan, as the latter requires more than set theory.
