$2.)$ You decide to write $($sell$)$ a call option on a share of NVDA stock at a strike price of $$100.$ You sell it for $$10.$ You do NOT buy shares in the stock. Tomorrow is the expiration date.

a$.)$ What is the net cash flow into or out of your account today?

$$10$

b$.)$ The price rises to $$120$ per share. What would be the total net cash flowing into or out of your account in this case including what happens on the first day.

c$.)$ Same question, but assume the price falls to $80.$
