Answer:
B. Write a put option on $10 million worth of Exxon Mobile
Step-by-step explanation:
In order to hedge or reduce the risk Mr Saso should be writing a put option as it permits to sell the stock at the price i.e. predetermined. In case when there is a drop in price that falls the position so it would not be destroyed and therefore the profits could be made
The other option i.e. c and d are not correct as there is no requirement of call option and also long position
And, the option a is also wrong because in this it considered buying the particular amount not for selling it
Hence, the correct option is B
