Identify the clause of the highlighted expression of the following sentence:

Ram knows that Lalit is going to help him.

Correct option is B

The correct answer is (b) Noun Clause.
Detailed Explanation (English): In the sentence “Ram knows that Lalit is going to help him,” the highlighted expression “that Lalit is going to help him” acts as the object of the verb knows. Any clause that functions as a noun (subject or object) in a sentence is called a Noun Clause.
Here, “Ram knows what?” → “that Lalit is going to help him.” Since it answers the question what? (object of the verb), it is a noun clause.
Grammatical rule used: A Noun Clause begins with conjunctions like that, what, whether, if, who, etc., and acts as a subject, object, or complement in a sentence.
Explanation of the grammatical rule in Hindi: जब कोई उपवाक्य (clause) वाक्य में संज्ञा (noun) का कार्य करता है — अर्थात् कर्ता, कर्म या पूरक के रूप में आता है — तो उसे Noun Clause कहते हैं। यहाँ “that Lalit is going to help him” क्रिया knows का कर्म (object) है।
Example:
· I believe that he is honest. → “that he is honest” = Noun Clause (object of believe).
Meanings of other options: · Principal Clause: the main independent clause in a sentence (मुख्य उपवाक्य)। · Adjective Clause: modifies a noun or pronoun (संज्ञा या सर्वनाम का वर्णन करता है)। · Adverb Clause: modifies a verb, adjective, or adverb (क्रिया, विशेषण या क्रिया विशेषण का वर्णन करता है)।
