When you enumerate you need to put comas between all the items except the ones which are connected by "and" : as A is not correct as it does not have comas, and B is incorrect as it has comas where "and" is.
now, in a way both C and D are correct, but C is the usual accepted version, and D is an example of "Oxford coma" (where the coma is optional, to remain on the safe side, choose C).
This is an example. None of this really happened. (I have a dog)
Ex:
<em>"It was a crisp, cold, dark night if I remember correctly. I was rushing my parents out the door and into the car so we could go to the vet. Our cat got hit by a car a couple blocks away and someone brought her to the vet. I was relived because if our cat didn't have a microchip they probably would've taken my cat! I was so scared. My heart was beating super fast, my palms were sweaty. Anyway, as I got there my stomach sank. I hated the vet, the doctor, etc. The vet asked if we were the owners and then took us to the room he was in. He wasn't hurt too bad. He broke his paw, but he'll manage. Moral of the story, is I will never forget how scared I was."</em>
