Explanation:
<u>Relative clauses are those groups of words or phrases that have a subject and a verb in it but is unable to be deemed a full sentence on its own</u>. It is also similar to a dependent clause and needs an independent clause to be a full, correct sentence and is also known as an <u>"adjective clause"</u> as they act as adjectives in the sentence.
Among the options given in the question, <u>sentence 1, 2, and 4</u> contains relative clauses in them. In sentence 1, the relative clause<u> "which grow in warm climates" describes/ modifies the noun "palm trees"</u> while <u>"that has a built-in camera" modifies "the laptop" </u>in sentence 2. Likewise, sentence 4 contains the relative clause <u>"who led us through the canyon" modifying the noun "the guide"</u>. They <u>also contain a subject and a verb in each of them</u>, thus making them relative clauses.
Thus, the <u>correct answers are options 1, 2, and 4.
