A Correct answer
Explanation

The pattern is n×8. 7×8=56. For 9: 9×8=72, but the answer given is 90. Let me re-check. Actually, looking at the options, 90 doesn't fit n×8. Alternative: 7×8=56, 9×10=90 gives multiplier increases by 2 (8,10). This makes sense as a pattern where multiplier = first number +1: 7+1=8, 9+1=10. So 9×10=90, option A.

AI explanation

To answer this question, let's analyze the relationship between the given numbers.

If we observe the relationship between 7 and 56, we can see that 7 is multiplied by 8 to get 56 (7 * 8 = 56).

Using the same logic, we can determine the relationship between 9 and the options:

A) 90: 9 * 10 = 90 B) 81: This option is not obtained by multiplying 9 with any number. C) 100: This option is not obtained by multiplying 9 with any number. D) 110: This option is not obtained by multiplying 9 with any number.

Therefore, the correct answer is A) 90, as it is obtained by multiplying 9 by 10.
