Solution

The correct option is B $5$ and $9$
Let x be the number of three digits and y be the one got after reversing the digits of x, then we know that $(x - y)$ is always divisible by $99$ .
Since the unit digit of the required number is $4$ so it has to be $99 \times 6 = 594$ . Thus, the other two digits are $5$ and $9$ .
