'Those' is a demonstrative adjective that refers to plural nouns, but 'paint' is a singular noun. Hence the statement needs to be corrected. Option D, as well as Option C, is incorrect. 'That' demonstrates singular nouns (in this case paint) and the grammatical structure of Option B is the same as that of the phrase 'paint on the original statue', option B is the correct answer. Option A has one noun, 'reproduction' and is incomplete since 'paint' is not mentioned nor is its demonstrative, making it an incorrect option.
