Solution

The correct option is B $9$
The given ratio table is,

3 6 9 15

4 9 12 20

The first ratio is $3 : 4$ .

The next ratio should be equivalent to $3 : 4$ .

$\frac{3 \times 2}{4 \times 2} = \frac{6}{8}$

The ratio given in column $2$ is $6 : 9$ .

Hence, the number incorrectly entered is $9$ .
