Show answer & explanation

Correct answer: A

A Δ B represents symmetric difference, equal to (A − B) ∪ (B − A), matching III. A − (B ∪ C) simplifies to (A − B) ∩ (A − C), matching II. A − (B ∩ C) expands to (A − B) ∪ (A − C), matching I. A ∩ (B − C) is equivalent to (A ∩ B) − (A ∩ C), matching IV. Thus, the correct sequence is A-III, B-II, C-I, D-IV.
