Sagot :

Answer:

letter A

Step-by-step explanation:

1.A

not sure correct me if I'm wrong

Answer:

D

Step-by-step explanation:

Cant be A cuz 3x9 = 27 not divisible by 2

Cant be C cuz 2x9 = 18 and 8 is an even number

Cant also be B because 12 is not divisible by 9

But letter D:

1x9 = 9

2x9 = 18 = 1+8 = 9

3x9 = 27 = 2+7 = 9

4x9 = 36 = 3+6 = 9

5x9 = 45 = 4+5 = 9

6x9 = 54 = 5+4 = 9

7x9 = 63 = 6+3 = 9

8x9 = 72 = 7+2 =9

9x9 = 81 = 8+1 = 9

10x9 = 90 = 9+0 = 9

The digits of the multiples of 9 will also create 9
