Final answer:
The homonyms in this question are 'their' and 'they're'.
Step-by-step explanation:
The correct answer is OC. Their and they're.
Homonyms are words that have the same spelling or pronunciation but different meanings. 'Their' is a possessive pronoun that shows ownership, while 'they're' is a contraction of 'they are'.
For example, in the sentence 'Their house is big', 'their' is used to show that the house belongs to a group of people. In the sentence 'They're going to the party', 'they're' is a contraction of 'they are' and means that the group of people is going to the party.
