The formula for put-call parity is:C + K = P + FC is the price of the call optionK is the strike price of the optionP is the price of the put optionF is the price of the underlying asset

Put Call Parity

The holder of an option contract is not mandated to exercise the option. If the market movement is adverse, he or she may stay out of exercising the contract. However, the writer of an option contract must exercise his side of obligation in case the holder exercises the option. Thus, options create one sided obligation.
