Answer:
1.who owns a red car
2.that ate my homework
3.that have cherries
4.that she gave them
Explanation:
A restrictive clause gives information about a noun in a sentence without separating them with commas. They modify the noun that comes before them and change the meaning of the sentence if removed.
Therefore, the four restrictive clauses from the sentences are:
1. who owns a red car
2.that ate my homework
3.that have cherries
4.that she gave them
