Solution:
To solve this question, we need to use the concept of the LCM (Least Common Multiple) of the given numbers.
LCM of 2 and 8 is 8.
Therefore, any number that is divisible by both 2 and 8 must be a multiple of 8.
I. N is divisible by 4
If a number is divisible by 8, it is also divisible by 4. Therefore, statement I is true.
II. N is divisible by 6
If a number is divisible by 8, it is not necessarily divisible by 6. Therefore, statement II is false.
III. N is divisible by 16
If a number is divisible by 8, it is not necessarily divisible by 16. Therefore, statement III is false.
Therefore, the only statement that must be true is statement I, and the correct answer is option A.

The correct answer would be A.
Explanation : N is divisible for 4 since 4 is a factor of 8 and the number would be divisible by 8.
For a number to be divisible by 6 it should be divisible by both 2 and 3 hence it would not be divisible by 6.
now if the number is divisible by 2 and 8 it is not necessary to be divisible by 16 .
