    The second number is obtained by adding the square of the difference of the digits of the first number to the first number itself. Option A: 52 – 61 → 52 + (5 – 2)² = 52 + 9 = 61 Option B: 84 – 100 → 84 + (8 – 4)² = 84 + 16 = 100 Option C: 63 – 72 → 63 + (6 – 3)² = 63 + 9 = 72 Option D: 95 – 120 → 95 + (9 – 5)² = 95 + 16 = 111
