Choose the option that correctly identifies the (underlined) words in each sentence.

I love telling people about Jodi Picoult, (whose books are always bestsellers.)
a. subordinate clause
b. adjectival clause
c. independent clause
d. adverbial clause

*I think its b, but I'm not sure.* please help....

"b" is correct.

Adjective clauses almost always begin with relative pronouns (and yes, "whose" is one of them) and describe or modify the closest noun, in this case "Jodi Picoult."

To identify the type of clause used in the underlined section of the sentence, we need to understand the function it serves.

In the given sentence, the underlined clause provides additional information about Jodi Picoult. It describes the books written by Jodi Picoult.

Now, let's analyze the options to determine the correct answer:

a. Subordinate clause: A subordinate clause cannot stand alone as a complete sentence, and it functions as a dependent clause in the sentence. It typically begins with subordinating conjunctions like "although," "because," "when," etc. This does not apply to the underlined clause in the given sentence.

b. Adjectival clause: An adjectival clause, also known as a relative clause, modifies a noun or pronoun in the sentence. It answers questions like "which one?" or "what kind?" The underlined clause in the sentence modifies and provides more information about Jodi Picoult. This option could potentially be correct.

c. Independent clause: An independent clause can function as a standalone sentence because it expresses a complete thought. It contains a subject and a predicate. The underlined clause in the sentence does not fulfill these criteria.

d. Adverbial clause: An adverbial clause, as the name suggests, functions as an adverb, modifying a verb, adjective, or another adverb in the sentence. It typically begins with subordinating conjunctions like "when," "because," "although," etc. The underlined clause does not function as an adverb in the sentence.

Based on the analysis, the correct answer is b. adjectival clause because the underlined clause modifies the noun "Jodi Picoult" by providing additional information about her books.
