On (A={1,2,3,4,6,12}), (R={(a,b):a) divides (b)(}). Which statement about ((3,12)) and ((12,3)) is correct?

Answer and explanation

Correct answer: ((3,12)) is present but ((12,3)) is absent

Step 1: (3) divides (12), so ((3,12)) belongs to the relation. Step 2: (12) does not divide (3), so ((12,3)) does not belong. Step 3: This is why the divisibility relation is generally not symmetric.
