The sentence revision is: Nikita would like to know which car is theirs.
The possessive pronoun here is <em>theirs.</em>
<em>Theirs</em> replaces<em> belongs to Yosef and Taiga.</em>
Possessive pronouns help to show possession or ownership in a sentence. There are two types of possessive pronouns;
- the strong ( absolute ) possessive pronouns: mine, your, his, her, its, ours, yours and <em>theirs</em>. Their refer back to a noun already used replacing it to avoid repetition.
- the weak possessive pronouns : my, your, his, her, its, our, your, their. They function as determiners in front of the noun to to describe who something belongs to.
