Answer:
The correct answer is (a) "cookies is milk, there's something special".
Step-by-step explanation:
The correct answer is (a) "cookies is milk, there's something special". The subject "cookies" is plural, and the verb "is" is singular, which results in a subject-verb agreement error. The verb should be "are" to agree with the plural subject. The corrected sentence would be: "The best thing to drink with cookies are milk, there's something special about the combination of milk and cookies." However, the better way to revise the sentence would be to use "there is" instead of "there are," since "something" is singular. This results in the corrected sentence: "The best thing to drink with cookies is milk, there's something special about the combination of milk and cookies."
