Identify the highlighted clause used in the given sentence.
We asked him many questions when we met him.

Correct option is C

The correct answer is (c) Adverb Clause.
• The highlighted part is “when we met him”.
• It begins with when, which is used as a subordinating conjunction introducing a time clause.
• This clause tells when we asked him many questions (time of the action).
• A clause that modifies the verb of the main clause by telling time/place/reason/manner is called an Adverb Clause.
Grammatical Rule Used (English):
• Adverb Clause modifies the verb of the main clause and answers: when/where/why/how.
• “when” introduces an Adverb Clause of Time.
Grammatical Rule Used (Hindi):
• जो उपवाक्य मुख्य वाक्य की क्रिया के बारे में समय/स्थान/कारण/रीति बताता है, वह Adverb Clause कहलाता है।
• “when” समय बताता है, इसलिए “when we met him” समयवाचक क्रिया-विशेषण उपवाक्य है।
