Explanation:

Both statements are incorrect.

• The types of disabilities have been increased from existing 7 to 21 and the Central Government will have the power to add more types of disabilities.
• The Act provides for grant of guardianship by District Court under which there will be joint decision – making between the guardian and the persons with disabilities.
• A guardian is a person who is appointed to look after another person or his property. He or she assumes the care and protection of the person for whom he/she is appointed the guardian. The guardian takes all legal decisions on behalf of the person and the property of the ward.

Hence option 4th is correct.
