Explanation:

Step1: Calculate proportion of girls

The proportion of girls is $\frac{710}{1400}\approx 0.5071$.

Step2: Compare with expected proportion

The expected proportion of girls in random births is around 0.5. Since $0.5071$ is close to $0.5$, it is within a reasonable range.

Answer:

B. The number of girls is neither significantly low nor significantly high.
