Question

Select the noun clause and state its purpose in the sentence:
He admitted that he made a very big mistake.

• A. He admitted - subject
• B. that he made a very big mistake - complement of a verb
• C. admitted that he made - apposition to the pronoun
• D. no option

Answer 1

The correct option is B that he made a very big mistake - complement of a verb

A noun clause is a dependent clause that functions as a noun. It usually begins with what, whatever, whom, that and other such relative pronouns. A noun clause can act as a subject, object, predicate nominative or object of a preposition, in a sentence.
A verb complement is a word, a phrase or a clause that is added to the verb to complete its meaning.
The noun clause "that he made a very big mistake" is a verb complement; the verb "admitted" makes no sense if it isn't followed by a word that complements it. The noun clause in B functions as a verb complement, hence it is correct.
Option A is incorrect because it isn't a noun clause nor is it the subject; it contains the verb "admitted" and noun clauses do not contain the main verb.
Option C is incorrect because it is a part of the noun clause with the verb "admitted".
Option D is incorrect because the answer lies in B.
