Can anyone explains these question about options in easy and simple language

From a buyer’s perspective

  1. What happen if my Call or Put option ( That i purchased after giving a fixed premium)
    a) is ITM on the day of expiry
    b) is ATM on the day of expiry
    c) is OTM on the day of expiry

  2. Similarly if i am writing option what will happen if the call or Put that i sold is

a) is ITM on the day of expiry
b) is ATM on the day of expiry
c) is OTM on the day of expiry

Everything boils down to the price at which you bought/ sold.

There’s no guarantee that you make a profit from the moneyness alone
