Final answer:
The character who is a servant, speaks in a Yorkshire accent, and is religious yet unkind in Emily Brontë's novel Wuthering Heights is Joseph.
Step-by-step explanation:
The character described in the question is a servant who speaks with a Yorkshire accent and is religious yet unkind. The correct answer is b) Joseph from Emily Brontë's novel Wuthering Heights. Joseph is known for his devout religious fervor and grumpy demeanor, often expressing himself in a thick Yorkshire brogue that can be difficult for others to understand.
Unlike Heathcliff, who is also a central character in the novel but is not particularly known for religious fervor, Joseph represents the characteristics of fervent religiosity coupled with a lack of kindness. He is neither the protagonist nor presented as a landlord-like figure such as Lockwood or Hindley Earnshaw, the other options listed in the question.
