Concept:Apply the same whole-number operation to each given number.The logic is: multiply by 3, then add 2.Explanation:Check the first pair: 24→7424×3=7272+2=74So the relation holds.Check the second pair: 36→11036×3=108108+2=110So the same logic works.Now apply this logic to 51:51×3=153153+2=155Hence, 51 is related to 155.Answer:Option 2: 155
