Identify the following Clause:He did his homework and went to bed when I reached home.

Explanation

The correct answer is option B, 'Dependent clause.' A dependent clause, such as 'when I reached home,' cannot convey a complete thought on its own and thus relies on an independent clause to form a complete sentence. In contrast, option A is incorrect because 'He did his homework and went to bed' is an independent clause that can stand alone. Option C is incorrect since an adjective clause modifies nouns, and 'when I reached home' does not serve that purpose. Lastly, option D is incorrect because 'preposition clause' is not a recognized grammatical term, and the phrase does not function as a preposition clause.
