5%
7%

27%

Explanation:

Step1: Find the percentage of baby - girls born

If 56% of the babies born are not girls, then the percentage of baby - girls born is $100 - 56=44\%$.

Step2: Find the percentage of premature baby - girls

We know that 12% of the baby - girls born are premature. So the percentage of premature baby - girls is $0.44\times0.12$.
$0.44\times0.12 = 0.0528$.

Step3: Round the result

Rounding 0.0528 to the nearest percent gives 5%.

Answer:

5%
