Correct Answer: Option A ) 1 & 2 only
The Indus River basin is one of the major river systems in Asia, and understanding its political geography is important:
A third of the Indus basin lies in India - This statement is correct. Approximately one-third (about 33%) of the total Indus basin area falls within Indian territory, while the majority (around 52%) lies in Pakistan.
It covers parts of Ladakh, Jammu & Kashmir, Punjab, and Himachal Pradesh - This statement is correct. Within India, the Indus basin covers these four territories/states. The Indus River itself originates near Lake Manasarovar in Tibet and flows through Ladakh before entering Pakistan.
The majority of the Indus basin lies in Afghanistan - This statement is incorrect. While a small portion of the Indus basin (about 6%) does extend into Afghanistan through the Kabul River (a tributary of the Indus), the majority of the basin is actually in Pakistan, not Afghanistan. China also contains about 8% of the basin area.
