On the set (A={1,2,3,4}), the relation (R={(a,b):a-b\text{ is divisible by }2}) is given. Choose the correct statement about this relation.

Answer and explanation

Correct answer: (R) is an equivalence relation

Step 1: For every element, (a-a=0), which is divisible by (2), so the relation is reflexive. Step 2: If (a-b) is divisible by (2), then (b-a) is also divisible by (2), so it is symmetric. Step 3: If (a-b) and (b-c) are divisible by (2), then (a-c) is also divisible by (2). In exams, test all three properties separately.
