To calculate the centered 4-point moving average for a given quarter, we take the average of the current quarter and the previous two and next quarter. 
For the given quarter, we have data for Q2-2018, Q3-2018, Q4-2018, and Q1-2019. 
So, the centered 4-point moving average for Q3-2018 would be: 
(197.09 + 192.51 + 198.93 + 197.16)/4 = 196.92 
Therefore, the answer is B) 110.64.
