Choose the correct answer:

Assertion(A): Salinity is higher in closed ocean basins.

Reason(R): Enclosed ocean basins undergo little mixing with the open ocean.

OPTION A is correct since closed ocean basin like the Mediterranean basin is more saline than the open Ocean basins. This is because, these enclosed basins undergo little mixing with the open ocean and they experience much larger surface temperature due to the proximity with land. Hence, both A and R are correct, and R explains A.

OPTION A is correct as in enclosed basins salinity is higher because of thje they undergo little mixing with open oceans.

OPTION B is wrong as R explains A

OPTION C is wrong as R is true.
