The Maternity Benefit (Amendment) Act, 2017 has brought substantial changes to female workers` entitlements in India.

Option 1 is incorrect. Under the Act, women are entitled to 26 weeks of maternity leave, not 3 months pre and post-delivery. It`s an extension from the previous provision of 12 weeks.

Option 2 is incorrect as well. Enterprises with creches must allow mothers to visit, but the Act does not specify that a minimum of six visits must be made daily.

Option 3 is correct. The act does state that a woman is entitled to the full 26 weeks of paid leave for her first two children. For more than two children, the entitlements are reduced to 12 weeks.

So, only statement 3 is correct and hence option 3 is the answer.
