Final answer:
The statement about Fezziwig being a covetous old sinner is false; in Dickens's 'A Christmas Carol', he is actually a generous and kind-hearted character.
Step-by-step explanation:
The character Fezziwig is from Charles Dickens's novel A Christmas Carol. The statement that Fezziwig was a "squeezing, wrenching, grasping, scraping, covetous old sinner" is False.
Fezziwig is depicted as a kind-hearted, generous and jovial character, who is very much the opposite of the description given in the question. He is known to have treated his apprentice, Ebenezer Scrooge, with kindness and compassion, throwing annual Christmas parties for his employees to enjoy. Therefore, this representation of Fezziwig as a negative character is incorrect.
