Answer:
Option A.$250,000, is correct answer
Step-by-step explanation:
In order to determine the amount that would be debited to construction in process account for additional cost due to change from completed contract method to percentage of completion method,we need to ascertain the costs charged in years 2013 and 2014 under the old method compared the costs that should have been charged under the new method
Costs charged in 2013 and 2014=$300,000+$200,000=$500,000
Costs that should have been charged =$500,000+$250,000=$750,000
Increase in cost due change=$750,000-$500,000=$250,000
