Explanation:

Under the Rights of Persons with Disabilities Act, 2016, disabilities have been increased from 7 to 21.

• Only the Central Governments will have the power to add more types of disabilities.
• State governments must take measures to minimise the impact of disability.
• Every child with benchmark disability between the age group of 6 and 18 years shall have the right to free education.

Hence only statement 2nd is correct.
