Select the triad from among the given options that is analogous to the given triad.
251 – 332 – 422

​The given triad is: 251 – 332 – 422,

Logic:  the sum of the digits for each number is 8

251 → 2 + 5 + 1 = 8

332 → 3 + 3 + 2 = 8

422 → 4 + 2 + 2 = 8

Now, checking the options:

Option A: Sum of digits is not 8.

Option B: Sum of digits is not 8.

Option C: Sum of digits is not 8 for all numbers.

Option D:161 → 1 + 6 + 1 = 8, 512 → 5 + 1 + 2 = 8, 710 → 7 + 1 + 0 = 8.

Thus, the correct answer is (D) 161 – 512 – 710.
