Correct answer: B

Asian options are most useful when the buyer wants to hedge or reduce the effect of price fluctuations over time.

• A hedger with a series of fluctuating forward input costs benefits from averaging, because the payoff is tied to an average price rather than a single spot price at maturity.
• They are less desirable for speculators because averaging reduces the chance of extreme payoffs.
• They are also less appropriate for a single lump-sum cost, where a standard vanilla option may be more suitable.
• A short would not generally want to buy a more expensive structure to increase premium unless there is some specific risk management objective.

Therefore, the most likely desirable use is B.
