Study the given pattern carefully and select the number from among the given options that can replace the question mark (?).

Correct option is A

Logic: square of 2nd + 1st = 3rd
5² + 5 = 29
25 + 4 = 29
29 = 29
And
7² + 6 = 55
49 + 6 = 55
66 = 55
Similarly,
9² + 8
= 81 + 8
= 89
Correct answer is (a) 89
