The sex ratio in Assam has shown improvement in recent Census surveys due to:

The correct answer is: d) All of the above.

The sex ratio in Assam has shown improvement in recent Census surveys due to a number of factors, including:

• Reduction in female infanticide: Female infanticide is the practice of killing female infants at or shortly after birth. It is a form of gender-based violence that is often motivated by a desire to have a son. In recent years, there has been a significant decline in female infanticide in Assam, due to a number of factors, including increased awareness of the practice, improved law enforcement, and changes in social attitudes.
• Better healthcare access: Improved healthcare access has led to a decline in maternal and infant mortality rates, which has also contributed to the improvement in the sex ratio. When women and children have access to quality healthcare, they are more likely to survive and thrive.
• Awareness campaigns: Awareness campaigns have been launched to educate people about the importance of girls and to discourage harmful practices such as female infanticide. These campaigns have been successful in raising awareness of the issue and changing attitudes towards girls.

The improvement in the sex ratio in Assam is a positive development, but there is still more work to be done. The state government and civil society organizations need to continue to work to ensure that all girls have access to quality education, healthcare, and opportunities.
