• A. $3225$
• B. $2872$
• C. $2971$
• D. $2874$

Answer 1

The correct option is A $3225$

We know the divisibility rule for $15$: If a number multiple of both $3$ and $5$, then the number is multiple of $15$.
Here $3+2+2+5=12$, which is multiple of $3$, so $3225$ is divisible by $3$.
The last digit is end with $5$, so $3225$ is divisible by $5$.
Therefore, $3225$ is divisible by $15$.

So, option A is correct.
