Calculating 2019 Current Account Trade Balance

Steps:

• Identify exports and imports from 2019 data: exports = $500,000m, imports =$358,000m.
• Apply trade balance formula: exports minus imports.
• Compute: $500,000m -$358,000m = $142,000m surplus.
• Confirm value in millions ($m) as positive for surplus.

Why B is correct:

• Trade balance on current account is defined as exports of goods/services minus imports, yielding $142,000m for 2019 per standard formula.

Why the others are wrong:

• A: Understates surplus by ignoring full export value.
• C: Overstates by adding unrelated current account transfers.
• D: Overstates further by including capital account flows.

Final answer: B
