Commodity options are option contracts written with a particular commodity futures contract as the underlying asset. A commodity option buyer has purchased the right, but not the obligation, to purchase a futures contract at the strike price of the option. The seller of the commodity option, has accepted the burden of "delivering" the underlying futures contract at the named strike price of the option.
"Commodity Options" is also the title of a book written by Carley Garner which outlines several commodity option trading strategies.
