Answer:
Decrease;decrease.
Explanation:
In Business, an option is a legal contract which gives a buyer the right but not an obligation, to sell (such as put) or buy (such as a call) the underlying asset at a specific or given price on or before a certain date.
Generally, buyers of put options anticipate the value of the underlying asset will decrease, and sellers of call options anticipate the value of the underlying asset will decrease.
