Are you looking at the original exam question or are you looking at it in a Revision Kit?
The reason I ask is that in the original question there are no futures available – the choices are to use forward rates, to use the money markets, or to use options.

With traded options, then strictly the transaction should be converted at whatever spot happens to be on the date of the transaction. If there is a gain comparing the spot rate and the exercise price then the option will be exercised. (There is never a loss because if there were then the option would simply not be exercised)

Here, we do not know what the spot rate is on the date of the transaction and therefore if the option is exercised then we must simply convert the contract amount at the exercise price.
