Match List I (identity) with List II (name). List I: A. x + x = x, B. x + 0 = x, C. x + 1 = 1, D. x + xy = x. List II: I. Identity law, II. Absorption law, III. Idempotent law, IV. Domination law.

1. AA ‐ III, B ‐I , C ‐ II, D ‐ IV
2. BA ‐ I, B ‐III , C ‐ IV, D ‐ II
3. CA ‐ III, B ‐I , C ‐ IV, D ‐ II
4. DA ‐ III, B ‐IV , C ‐ I, D ‐ II (X, *)

Show answer & explanation

Correct answer: C. A ‐ III, B ‐I , C ‐ IV, D ‐ II

Explanation

x + x = x is idempotent; x + 0 = x is the identity law; x + 1 = 1 is domination; x + xy = x is absorption.
