Correct Answer - Option 1 : 8

__Concept:__

nth term of A.P are a, a + d , a + 2d, . . . . ,a + (n-1)d .

Tn = a + ( n - 1 ) d

Where a = first term and d = common difference

__Calculation:__

Two-digit numbers are divisible by 12 are 12, 24 . . . . 96

Last number is 96

As we know that , Tn = a + ( n - 1 ) d

⇒ 96 = 12 + ( n - 1 )12

⇒ 84 = ( n- 1 )12

⇒ 7 = n - 1

⇒ n = 7 + 1 = 8.

The correct option is 1
