Why C

is the answer choice C because it is giving another example of why the home would be more likely to get damaged?

Hi, C is indeed correct because it gives an example of why that particular wood house was more likely to get damaged. E is wrong because it applies equally to the masonry and the wood houses. We are looking to explain the surprise result that the wood was damaged and the stone was not, so we would need to show that this wood house was in some way lesser or that the stone was in some way better than average. E doesn't do this.
