Options

• {b, c}

• {c}

• {a, b}

• {a, b, c}

Answer 1

Let A = {a, b, c}, then the range of the relation R = {(a, b), (a, c), (b, c)} defined on A is {b, c}.

Explanation:

Because the ordered pair's y-coordinate represents the range (x, y). As a result, the supplied relation's range is {b, c}.
