Explanation:

Both statements are incorrect.

• Slavery was abolished across the British Indian Empire during the tenure of Lord Ellenborough as Governor-General.

• The Charter Act of 1833 paved the way for the abolition of slavery across the British Indian Empire. Subsequently, in 1843, the Indian Slavery Act was passed, making slavery illegal throughout India. At the time, Lord Ellenborough served as Governor-General.

• Article 23 of the Indian Constitution prohibits human trafficking and forced labor, safeguarding individuals from exploitation and ensuring their right to freedom and dignity. 

• Traffic in human beings and beggars and other similar forms of forced labor are prohibited and any contravention of this provision shall be an offense punishable in accordance with law.

Hence option 4th is correct.
