Answer: net exports
Step-by-step explanation:
Balance of payment simply shows the estimation of the inflows and outflow of a nation's money for a certain year. It should be noted that current account of the balance of payment consists of three main components which are the trade in Goods, the trade in services, and the transfer payments.
The trade in goods is segregated into imports and export. This therefore makes the net exports volatile and vital because it has higher share in a current account.
