With reference to the India–Sri Lanka fisheries dispute, consider the following statements:

1. The International Maritime Boundary Line (IMBL) is relevant not only to fishing rights but also to the exercise of maritime jurisdiction and regulation of resource use.
2. The dispute over fishing rights is independent of ecological concerns associated with bottom trawling.
   Katchatheevu lies in the Palk Strait and was ceded to Sri Lanka in 1974.
3. Indian fishermen are permitted to use Katchatheevu for drying nets and resting, but this does not amount to unrestricted fishing rights around the island.

Which of the statements given above are correct?

Consider the following statements regarding the proposed alternatives to dollar-centric international payments among BRICS countries:

1. Correspondent banking arrangements can involve conversion through a dominant currency when direct banking links between two countries are absent.
2. Increasing intra-BRICS trade can create greater demand for payment mechanisms that are cheaper and faster than conventional correspondent banking arrangements.
3. A reduction in dependence on the U.S. dollar necessarily implies that BRICS countries would cease using the dollar in international trade.
4. Greater use of national currencies in cross- border payments can reduce the need for some foreign-exchange conversions and intermediary transactions.

Which of the statements given above are correct?

With reference to Navier–Stokes equations and the associated Millennium Prize problem, consider the following statements:

1. Navier–Stokes equations treat fluids as continuous media rather than describing the motion of individual molecules.
2. The Millennium Prize problem concerns, among other possibilities, whether solutions can develop a finite-time singularity.
3. The existence of a forcing function in the equations necessarily implies that a finite- time blow-up will occur.
4. A forcing function represents an external influence capable of adding momentum to a fluid.

Which of the statements given above is/are correct?

A policymaker proposes a package to reduce excessive sugar consumption in India. The package includes: mandatory front-of-pack warnings for high-sugar products, restrictions on marketing unhealthy foods to children, regulation of foods sold by informal vendors, and a tax that increases with the sugar content of a beverage.
