The correct option is D none of these

Numbers are divisible by $8$ if the number formed by the last three individual digits is divisible by $8$.

For example, the last three digits of the number $3624$ is $624$, which is divisible by $8$.

Therefore, $3624$ is divisible by $8$.

Hence, a number is divisible by $8$ if the number formed by the digit in units, tens and hundreds place is divisible by $8$. So, none of the given options is correct.
