Answer:
D
Step-by-step explanation:
Their = belonging to or associated with the people or things previously mentioned or easily identified.
There = in, at, or to that place or position.
The sentence in the question uses There instead of Their. They both sound the same but mean two different things. In this case, it would make it a misspelling instead of any of the other options.
