In the Flexible Exchange Rate System, the exchange rate is determined by market forces of supply and demand. Statement A is true, as the system does not require the government to maintain large stocks of foreign exchange reserves.
However, Statement B is false because, under this system, governments typically do not need to intervene directly to address balance of payment deficits, as the exchange rate adjusts automatically through market forces.
Thus, the correct answer is (1) A is true and B is false.
