Solution

The correct option is A 2 girls
Total no .of families $1500$
No .of families with $2$ children is $475$
Probability of picking them is $\frac{475}{1500} = \frac{19}{60}$

No .of families with $1$ children is $814$
Probability of picking them is $\frac{814}{1500} = \frac{407}{750}$

No .of families with $2$ children is $211$
Probability of picking them is $\frac{211}{1500}$
