Step 1: Understanding Balance of Payments Surplus.
A surplus in the Balance of Payments occurs when a country's Autonomous Receipts (inflows) exceed its Autonomous Payments (outflows).
Step 2: Evaluating the options.
- (A) Incorrect, as a surplus happens when receipts exceed payments.
- (B) Incorrect, as Current Account payments alone do not determine a surplus.
- (C) Incorrect, as Capital Account transactions do not fully represent BOP surplus.
- (D) Correct, since Autonomous Receipts exceeding Autonomous Payments creates a BOP surplus.
Step 3: Conclusion.
Thus, the correct answer is \( \mathbf{(D)} \).
