The management at PhoneUn considered the option to abandon when building their new manufacturing plant. The design of the plant allows it to be easily converted to manufacture other types of large machinery. If its new line of cars is poorly received, its plant should be easy to sell to another manufacturing company. In this example, the price at which they expect to sell the plant if things go poorly resembles:

the premium of a put option on the plant. the premium of a call option on the plant. the strike price of a put option on the plant. the strike price of a call option the plant.
