Final answer:
The subordinate clause in the sentence 'she felt sad whenever she saw the picture' is 'whenever she saw the picture.' This clause cannot stand alone and provides additional information to the main clause. Option b is the correct answer.
Step-by-step explanation:
The question asks to identify the subordinate clause in the sentence 'she felt sad whenever she saw the picture.' In English grammar, a subordinate clause, also known as a dependent clause, is a group of words that has both a subject and a verb but cannot stand alone as a complete thought.
In this case, the subordinate clause starts with the subordinating conjunction 'whenever,' signaling that it cannot exist independently and is providing additional information to the main clause.
The correct option is: b) whenever she saw the picture.
Subordinate clauses can serve different functions, such as acting as an adjective, adverb, or noun within a sentence. They are essential in providing more detail and complexity to a sentence. By identifying these clauses, one can better understand the structure and meaning of complex sentences.
