Explanation:

In the sentence "The children, who were lucky, got presents", the clause "who are lucky" is a nonrestrictive one.

It is not an appositive. Appositives are  nouns or noun phrases that rename another noun next to it. "Who are lucky" is not a noun or noun phrase, but a clause. It is nonrestrictive in the sense that it does not change the noun in a limiting way. Let's compare:

- The children, who were lucky, got presents. --> the clause comes between commas, it is nonrestrictive. It is only adding the information that all the children were lucky, since they got presents.

- The children who were lucky got presents. --> the clause is not surrounded by commas. It is restrictive, meaning that only specific children, only the ones who were lucky, got presents.

We can safely choose the following as answers for this question:

2. The sentence contains a nonrestrictive clause.

6. All of the children got presents.
