answer.
Explanation: this is correct
The correct answer is adjectival clause.
An adjectival clause is a dependent clause that works to describe a noun in a sentence. It is usually made of a group of words instead of one word only. All the words work together to modify the noun or pronoun.
A dependent clause contains a subject and a verb but it's not a complete sentence and it can not stand alone.
Adjectival clauses begin with a relative pronoun that connects them to the word they describe. The relative pronouns are: that, where, then, who, which, why etc.
In the clause<em> who are compassionate</em>, the<em> who</em> is the relative pronoun. The clause refers and modifies the noun appearing before in the sentence.
B. A possessive noun should have its instead of it's (which is a contraction for it is).
For A. Diana is a singular noun and the apostrophe should come after the r instead of after the s.
For C. The duck would've dunked ITS instead of IT'S beak since it is possessive.
For D. You do not need to put an apostrophe since theirs is already a possessive noun.
