To find the inflation rate, we need to calculate the percentage increase in CPI between the two years. 
Using the formula: Inflation rate = ((CPI year 2 - CPI year 1) / CPI year 1) x 100%
= ((216 - 180) / 180) x 100%
= (36 / 180) x 100%
= 20%
Therefore, the inflation rate in 2014 was 20% (Option D).
