Answer 1

The correct option is C 81

If the sum of the digits of a given number is 9, the number belongs to the multiplication table of 9.

Let’s find out!

Given number	Sum of the digits
12	1 + 2 = 3 (3 is not equal to 9)
73	7 + 3 = 10 (10 is not equal to 9)
81	8 + 1 = 9 (9 = 9)
46	4 + 6 = 10 (10 is not equal to 9)

Since the sum of the digits in 81 is 9, it belongs to the multiplication table of 9.
