Read the following context and choose the best option to answer the question.
Context: Not that the back yard is anything more than a disaster zone at this point . Albeit slightly less of a disaster zone than the front yard . Of course during the grinding the neighbor 's sprinkler line was ground up , so I had to make an emergency trip to Ace to get some PVC pipe ( we had 3/4 " , the neighbor 's was 1/2 " ) and connectors to make that repair . The fence guy sort of took over as I was cleaning up the chewed ends of the existing pipe .
Question: What may be the reason why the front and back yard was a disaster zone ?
Options: 
A. None of the above choices .
B. Because they first tried to do the job themselves .
C. Because they hired people that were clueless .
D. Because of the construction .
