Answer:

Determiners are words that come before a noun to give information about the noun. In this question, we are asked to select the correct determiner to fill in the blank for the sentence "That camera is ____."

The correct answer is option 'C' - "Mine."

Here's an explanation of each option and why they are correct or incorrect:

a) My - This determiner is used to show possession, but since the sentence is talking about the camera in general and not specifically belonging to the speaker, it is not the correct answer.

b) Her - This determiner is used to show possession by a female person, but since the sentence does not mention any specific person, it is not the correct answer.

c) Mine - This determiner is used to show possession without mentioning any specific person. It is the correct answer as it can be used to refer to something that belongs to the speaker without specifying the gender.

d) Your - This determiner is used to show possession by the person being spoken to, but since the sentence does not mention any specific person, it is not the correct answer.

In this sentence, we are talking about the ownership of the camera in general, without specifying any particular person. Therefore, the correct determiner is "Mine" (option 'C').

To summarize:
- The correct determiner for the sentence "That camera is ____." is "Mine" (option 'C').
- "Mine" is used to show possession without specifying any specific person.
- The other options are not correct because they either specify a person or do not match the context of the sentence.
