I haven't read/watched the play in a while but i am pretty sure it is either D: Scrooge shows pity for the Cratchit family members and their living situation. or B: Scrooge cannot bear to watch the Cratchit family celebrate Christmas.
I don't know this for sure but if an author has something to declare and they can't back it up it's just an idea. So if you want to identify the claim you have to have statistics and facts to prove what you're saying. But remember I am not am expert so whatever you think the answer is go with it. Hope this helps ;)
