Identify the Adjective Clause in the following sentence:

She bought a dress that had beautiful embroidery on it.

 that had beautiful embroidery on it

The correct answer is Option 2: "that had beautiful embroidery on it"

An adjective clause (also known as a relative clause) is a dependent clause that describes a noun or pronoun in a sentence. It usually starts with who, whom, whose, which, or that and provides more information about the noun.

 Option 1: "She bought a dress"
  This is the main independent clause (it makes sense on its own).
  It does not function as an adjective clause.

 Option 2: "that had beautiful embroidery on it"
  This clause starts with "that", which is a relative pronoun.
  It describes "a dress", telling us which dress she bought.
  Since it gives more information about a noun, it is an adjective clause.
  This is the correct answer.

 Option 3: "on it"
  This is just a prepositional phrase, not a clause.
  It does not contain a subject and verb, so it cannot be an adjective clause.

 Option 4: "a dress"
  This is just a noun phrase (a subject or object in a sentence).
  It is not a clause at all, so it cannot be an adjective clause.
