The correct option is D $29865$

We know the divisibility rule for $15$: If a number multiple of both $3$ and $5$, then the number is multiple of $15$.
Here $2+9+8+6+5=30$, which is multiple of $3$, so $29865$ is divisible by $3$.
The last digit is end with $5$, so $29865$ is divisible by $5$.
Therefore, $29865$ is divisible by $15$.

So, option D is correct.
