Answer 1

Answer:

the answer is option B 422679

Step-by-step explanation:

The divisibility rule of 3 and 9 is same.

The divisibility rule dor 3 is sum of all the digits of a number is divisible by 3 other wise the number is not divisible by 3

and

I said the divisibility rule for 3 and 9 is same so, the option B is 4+2+2+6+7+9 = 30 so, 30 is only divisible by 3 in this case and 30 is not divisible by 9

therefore the answer is option B which is 422679
