Question

What’s the correct answer

Answer 1

My best guess would be D. My mother's old house, the one that was owned by her family for generations, is deteriorating.

Hope this helps.

Answer 2

My Mother's old house, the one that was owned by her family for generations, i s deteriorating. ^^ ^^

D is the best answer choice because it is using an Interrupter meaning that the phrase inside the commas can be taken out and the sentence still makes sense.
