Answer 2

Divisibility rule of 6:A number that is divisible by both 2 and 3 is divisible by 6.

Divisibility rule of 2:A number that ends with digit 0,2,4,6 or 8 is divisible by 2.

Divisibility rule of 3:If the sum of digits of number is divisible by 3,then that number is also divisible by 3.

Now,let's solve the questions:-

a)67821: It is not divisible by 6 as it's not divisible by 2.

b)78134:(7+8+1+3+4) =23 that is not divisible by 3,so it's also not divisible by 6.

c)86432:(8+6+4+3+2)=23 that is not divisible by 3 so it's also not divisible by 6.

So,right option is None of these
