Option 1: Balance of Trade -> Refers to the difference between exports and imports of goods (visible items).
Option 2: Balance of Payment -> Broader concept including all economic transactions (goods, services, capital flows).
Option 3: Capital Account Deficit -> Relates to capital transfers and non-financial assets, not trade in goods.
Option 4: Net Invisibles -> Refers to balance of trade in services (tourism, insurance), not goods.
Hence, Option 1: Balance of Trade -> Balance of Trade specifically measures the difference between the monetary value of exports and imports of goods (merchandise/visible items) in a country during a specific time period. When exports exceed imports, it's a trade surplus; when imports exceed exports, it's a trade deficit. This is distinct from Balance of Payment which includes both visible trade (goods) and invisible trade (services), along with capital account transactions. -> correct
