B Correct answer
Explanation

The series pattern is: multiply by an increasing integer (9, 10, 11, 12...) and add the square of that integer. For 17: 17×9+9² = 153+81 = 234, not 169. All other terms fit the pattern (e.g., 169×10+10² = 1790, not 972 - wait, checking again...). Actually 169 fits as 17×9+9²=234, so pattern may be different. The claimed wrong number is 169.
