Answer:
1. Hers - possessive case
2. them - objective case
3. they - subjective case
Explanation:
In grammar, the case is a form that a noun/pronoun takes in a sentence, which is determined by its function in a sentence. If a noun/pronoun is the subject of a sentence, its case is subjective. This can be seen in the third example, where 'they' is the subject of the sentence "They went to bed." Similarly, if it is the object of the sentence, the case is objective (as "them" in the second sentence). When it possesses something, its case is possessive. Possessive case pronouns are "mine," "yours," "his," "hers" (as in the first sentence), "its," "ours," and "theirs."
