Tamil Nadu has a relatively favorable sex ratio compared to many other Indian states, meaning:

More females than males
More males than females
Equal number of males and females
Sex ratio data is unavailable

The correct answer is: a) More females than males.

Tamil Nadu has a sex ratio of 996 females per 1000 males, which is higher than the national average of 940 females per 1000 males. This means that there are more females than males in Tamil Nadu.

There are a number of reasons for this. One reason is that Tamil Nadu has a strong tradition of female education and employment. Women in Tamil Nadu are more likely to be educated and employed than women in other parts of India. This means that they are more likely to be able to support themselves and their families, and they are less likely to be forced into early marriage or childbirth.

Another reason for the high sex ratio in Tamil Nadu is that the state has a strong social safety net. There are a number of government programs that provide support to women and children, such as food subsidies, healthcare, and education. This helps to ensure that women and children have access to the resources they need to survive and thrive.

The high sex ratio in Tamil Nadu is a positive sign for the state. It suggests that women are valued and respected in Tamil Nadu, and that they have the opportunity to reach their full potential.
