Explanation:

September 19 marks the 60th anniversary of the Indus Water Treaty (IWT) between India and Pakistan.

• The Indus Waters Treaty (IWT) was signed in Karachi on 19 September 1960 by Jawaharlal Nehru and Ayub Khan. The World Bank, as the third party, played a pivotal role in crafting the IWT.
• The Treaty gives control over the waters of the three "eastern rivers" — the Beas, Ravi and Sutlej with a mean annual flow of 33 million acre-feet (MAF)  to India, while control over the waters of the three "western rivers" — the Indus, Chenab and Jhelum with a mean annual flow of 80 MAF to Pakistan.
• India was allocated about 16% of the total water carried by the Indus system while Pakistan was allocated the remainder.
• The treaty allows India to use the western river waters for limited irrigation use and unlimited non-consumptive use for such applications as power generation, navigation, floating of property, fish culture, etc.

Hence option 2nd is correct.
