In the sentence about filling the teapot, which pronoun refers to the teapot?

• A. That
• B. It
• C. This
• D. Them

Answer: (B)

The key idea here is pronoun reference: when you talk about something already mentioned, you replace the noun with a suitable pronoun that matches in number. For a single, inanimate object like a teapot, the natural pronoun is it. It is singular and neuter, so it cleanly stands in for the teapot in follow-up clauses, as in “The teapot is empty. It needs filling.” Using that or this would point to the object but isn’t the standard way to replace a single noun in a sentence about it, and them is plural, which doesn’t fit a single teapot.
