Based on this excerpt from a christmas carol by charles dickens, how did scrooge's attitude change on christmas day?

the chuckle with which he said this, and the chuckle with which he paid for the turkey, and the chuckle with which he paid for the cab, and the chuckle with which he recompensed the boy, were only to be exceeded by the chuckle with which he sat down breathless in his chair again, and chuckled till he cried.

shaving was not an easy task, for his hand continued to shake very much; and shaving requires attention, even when you don’t dance while you are at it. but if he had cut the end of his nose off, he would have put a piece of sticking-plaister over it, and been quite satisfied.

1- his laughter shows that he now enjoys his status as a rich man in his community.
2- he is nervous about having to face christmas celebrations.
3- he is excited because of his newfound joy in life and the company of others.
4- he is giddy because of the plan he has formed to trick the townspeople.
