Explanation:

About Sir Creek

• It is a 96 km long strip of water disputed between India and Pakistan in the Rann of Kutch marshlands.
• The dispute lies in the interpretation of the maritime boundary line between Kutch and Sindh.
• The Creek opens up in the Arabian Sea.
• The Creek was originally called Ban Ganga.
• Pakistan claims the line to follow the eastern shore of the estuary while India claims a centerline (differing interpretations of paragraphs 9 and 10 of the Bombay Government Resolution of 1914 signed between the then Government of Sindh and Rao Maharaj of Kutch).
• India insists the Sir Creek should be divided between the two countries according to thalweg principle. Under international law, a thalweg is the middle of the primary navigable channel of a waterway that defines the boundary line between states.
• The International Boundary in the Sir Creek area and International Maritime Boundary line (IMBL) between India and Pakistan have not been demarcated.

Hence all statements are correct.
