9 is related to 90 following a certain logic. Following the same logic, 12 is related to 156. Which of the following umber is related to 72 using the same logic?

​9 → 90, 12 → 156

72  → ?

Logic: Add 1 to the given number and then multiply it by the number itself to get its related number.

9 × (9 + 1) = 9 × 10 = 90

12 × (12 + 1) = 12 × 13 = 156

Option A:  6 → 6 × (6 + 1) = 6 × 7 = 42 ≠ 72

​Option B:  9 → 9 × (9 + 1) = 9 × 10 = 90 ≠ 72

​Option C:  7 → 7 × (7 + 1) = 7 × 8 = 56 ≠ 72

​Option D: 8 → 8 × (8 + 1) = 8 × 9 = 72

So, the number 72 is related to is 8.

Thus, the correct option is: (d)​​
