Assuming the prices given are at the end of the year, you calculate the inflation as:
inflation percent = change in prices in a year / price at the end of the previos year
inflation percent in 2014 = [price at the end of year 2014 - price at the end of year 2013] *100 / (price at the end of year 2013)
inflation percent in 2014 = [180 - 125] *100 / 125 = 40%
Answer: 44% (option C.)
