What bet rewards a large payout for successfully making every one of a set of multiple selections within a single wager?

• A. Parlay
• B. Round Robin
• C. Accumulator
• D. System Bet

Answer: (A)

A parlay is a single bet that links multiple selections together, and it pays out only if every selection wins. Because the odds of each leg are combined, the potential payout is much larger than betting on each selection separately. If any one selection loses, the whole parlay loses. That all-or-nothing, single-wager structure with a large payoff for perfect accuracy is exactly what this option describes.

Round robin setups remix the selections into several smaller parlays, not one single wager covering all. A system bet places multiple combinations to hedge risk and can pay out even if not every selection hits. An accumulator is a closely related term in some markets, but the phrasing here points to the classic parlay structure, where a single bet hinges on every leg winning.
