How does a 'Long Strangle' strategy differ from a 'Long Straddle' strategy in options trading?

[ A ]A Long Strangle uses only futures contracts without any option positions.

[ B ]A Long Strangle uses Out-of-the-Money (OTM) Call and Put options with different strike prices, making it cheaper to enter than a Long Straddle (which uses identical ATM strikes) but requiring a larger price move to become profitable.[ CORRECT ]

[ C ]A Long Straddle has capped upside profit, whereas a Long Strangle has unlimited downside loss.

[ D ]A Long Strangle is restricted exclusively to agricultural commodity derivatives.

Takeaway

A Long Strangle uses OTM calls and puts at different strikes, making it cheaper to enter than a Long Straddle's identical ATM strikes, but it requires a larger price move in the underlying to reach breakeven and turn profitable.

Derivation

Because both legs of a strangle are purchased out-of-the-money, their combined premium is lower than buying an ATM call and an ATM put (the straddle construction) — this lower upfront cost is the strangle's main appeal for volatility traders on a budget. But that lower cost comes with a trade-off: since neither leg starts with any intrinsic value, the underlying must move far enough to push one of the two OTM strikes into profitable territory before the position breaks even, meaning the strangle needs a bigger move than the straddle to become profitable at any given premium level. This cost-versus-required-move trade-off between the two non-directional volatility strategies is the specific comparison the exam is testing.

Why the others fail

A — A Long Strangle uses only futures contracts without any option positions.

A Long Strangle is constructed using purchased call and put options at different strikes, not futures contracts — futures carry linear, undefined payoff profiles unrelated to this options structure.

C — A Long Straddle has capped upside profit, whereas a Long Strangle has unlimited downside loss.

Both a Long Straddle and a Long Strangle have unlimited upside profit potential and losses capped at the total premium paid on both legs — this description of capped upside and unlimited downside is.

D — A Long Strangle is restricted exclusively to agricultural commodity derivatives.

Strangles and straddles are general options volatility strategies applicable to any optionable underlying, not a structure restricted exclusively to agricultural commodity derivatives.
