Question

Accepted Answer

Option 3, "जिसे आप ढूँढ रहे हैं, वह मैं नहीं हूँ," is the correct answer because it contains a 'विशेषण उपवाक्य' (visheshan upvakya - adjective clause).

Here's why:

*   **What is a 'विशेषण उपवाक्य' (Adjective Clause)?** An adjective clause is a dependent clause that modifies a noun or pronoun. It functions like an adjective, providing more information about the noun or pronoun it modifies. It typically begins with a relative pronoun (like *जो*, *जिसे*, *जिसका*, *जिसने*) or a relative adverb (like *जब*, *जहाँ*, *जैसे*).

*   **Why Option 3 is Correct:** In the sentence "जिसे आप ढूँढ रहे हैं, वह मैं नहीं हूँ," the clause "जिसे आप ढूँढ रहे हैं" modifies the pronoun "वह" (he/she/that). It tells us *which* "वह" is being referred to. Therefore, it functions as an adjective clause, describing the pronoun "वह."

Now, let's explain why the other options are incorrect:

*   **Option 1: ज्योंही पढ़ने बैठा, कोई आ गया।** This sentence contains an adverb clause of time (कालवाचक क्रियाविशेषण उपवाक्य). The clause "ज्योंही पढ़ने बैठा" describes *when* someone came. It modifies the verb "आ गया" (came), not a noun or pronoun.

*   **Option 2: जहाँ लहलहाते खेत थे, वहाँ बहुमंजिला भवन बन गए हैं।** This sentence contains an adverb clause of place (स्थानवाचक क्रियाविशेषण उपवाक्य). The clause "जहाँ लहलहाते खेत थे" describes *where* the multi-story buildings were built. It modifies the verb "बन गए हैं" (have been built), not a noun or pronoun.

*   **Option 4: गुरुजी ने कहा कि वे आज नहीं आएँगे।** This sentence contains a noun clause (संज्ञा उपवाक्य). The clause "कि वे आज नहीं आएँगे" functions as the object of the verb "कहा" (said). It acts as a noun, not an adjective. It tells us *what* the teacher said.

In conclusion, only Option 3 contains a clause that modifies a noun or pronoun, thus functioning as an adjective clause ('विशेषण उपवाक्य'). Therefore, Option 3 is the correct answer.
