Which law is represented by A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C)?
Answer and explanation
Correct answer: Distributive law
The displayed identity is the distributive law of intersection over union. It has the same pattern as algebraic distribution: A is distributed across the union inside the parentheses, producing (A ∩ B) ∪ (A ∩ C). The commutative law changes the order of sets, the associative law changes grouping, and the complement law involves complements such as A′. Therefore, option A is the only correct answer.
