Assertion (A): Ceiling on foreign exchange for a host of current account transaction heads was lowered in the year 2000. Reason (R): There was a fall in foreign currency assets also.

The correct answer is B because both the assertion and the reason are factually correct statements, but there is no causal link between them. Regarding Assertion A, the year 2000 saw the replacement of the Foreign Exchange Regulation Act (FERA) with the Foreign Exchange Management Act (FEMA). Under the new FEMA regulations, the government did indeed lower or rationalize the ceilings on foreign exchange for various current account transactions, such as foreign travel and gifts, to better manage the transition. Regarding Reason R, it is historically true that India experienced a temporary dip in its foreign currency assets during the year 2000. This was largely due to the impact of rising international crude oil prices and the fallout of the East Asian financial crisis affecting capital flows. However, B is the correct option because the lowering of ceilings was part of a broader structural policy shift toward the FEMA regime and was not a direct emergency reaction to the dip in foreign currency assets. The fall in assets was not the primary reason for the regulatory changes introduced in the year 2000.
