The correct answer is: D. No error
The sentence “Each one of the boys have paid the tuition-fee” is grammatically correct. The subject “each one of the boys” is plural, so the verb “have paid” is also plural. The object “the tuition-fee” is singular, but it is a direct object, so it does not need to agree with the subject in number.
The other options are incorrect because they contain grammatical errors. Option A, “Each one of the boys,” is missing a comma after “boys.” Option B, “have paid,” is singular, but the subject “each one of the boys” is plural. Option C, “the tuition-fee,” is missing an article.
