Identify the Adjective Clause in the following sentence: We visited my grandmother who had returned from a world tour last week.

we visited my grandmother who had returned from a world tour last week

who had returned

The correct answer is Option (2) → who had returned  Here's why: An adjective clause describes a noun or pronoun. In this sentence, the clause "who had returned from a world tour last week" describes the noun "grandmother". It provides additional information about the grandmother's recent activity. The remaining options ("we visited my grandmother", "from a world tour", "last week") are not clauses or don't directly describe the grandmother.
