Answer:
D) purchasing euro call options.
Explanation:
If Lazer purchased euro call options it would be basically buying the right to purchase euros at a specified currency exchange rate. This way Lazer would know what is the maximum amount it will have to pay for the euros it needs to cover its debts. The call option give the buyer the right to purchase the euros but not the obligation, so if the euro depreciates, then Lazer can simply decide to not use the call option.
